What is a laser beam dump?
Laser beam dumps absorb incident light and are used to capture unwanted beams. In the laboratory, they are used to stop stray laser beams. Beam dumps can also be used to contain a laser beam within a portion of an instrument.
What can block a laser beam?
Visible laser light can be blocked by anything that also blocks conventional light, such as a solid curtain, a wall, or even a sheet of paper.
What is the purpose of a beam dump?
The purpose of a charged-particle beam dump is to safely absorb a beam of charged particles such as electrons, protons, nuclei, or ions. This is necessary when, for example, a circular particle accelerator has to be shut down.
What is CERN beam dump?
A beam dump absorbs the energy of photons or other particles in an energetic beam.
What is beam stopper?
“A beam stopper is a mechanical safety device used to intercept a particle beam, to guarantee the personnel safety.
Can you disable a security camera with a laser pointer?
Unfortunately, the answer is yes and it applies to all surveillance cameras. If the criminals using infrared illuminator, powerful LED torch light or even a reflective board, the camera cannot catch the image during the nighttime.
Can a mirror stop a laser?
The actual answer is no, it can’t. Even a mirror that reflects 95% of a lethal laser beam will still absorb enough heat to burn. This causes the reflectivity to be gone almost instantly, but a scattered burst of light from the point of impact could still blind the shooter or his allies.
Can a laser burn skin?
Lasers can harm the skin via photochemical or thermal burns. Depending on the wavelength, the beam may penetrate both the epidermis and the dermis.
Can a laser go through blinds?
Ordinary roller blind material is rarely capable of stopping a laser beam and specially-designed laser blocking products are required.
Can laser penetrate water?
So, do laser beams actually work underwater? And the simple answer to that question is “yes,” they absolutely do. As long as the internal components aren’t exposed to the water, they’ll work just fine.
What did you observe when the laser beam hits the wall?
The wall, however, scatters the light in all directions due to diffuse reflection. (An apparently smooth wall looks very bumpy to a laser beam.) The reflected light is thus visible to the entire class as a spot on the wall.
Water-Cooled Laser Beam Dump
Water-Cooled Beam Dump 990-0820 blocks a CW or a pulsed laser beam. It is mainly intended for beams 2 inch wide.
Water absorbs much energy. So, the dump is best suited for beams of up to 1 kW. The wavelength range is from 0.1 to 30 µm.
Even if the non-reflective coating is damaged by high intensity pulses, the beam is not reflected back into an optical scheme.
The dump mounts on an M6 hole on its back.
Water-cooled laser beam dumps for low to high power
The BD Series are rugged and easy-to-use, simply plug the water-cooling and you’re ready to go! Like our high power HP Series, these beam dumps have a highly resistant absorber that can withstand several kW in continuous mode. Their very large aperture of 100 mm in diameter accommodates even the largest beams.
An isolation tube (available in option) helps reduce the back reflections.
2 models are offered: 4 kW and 12 kW.

Water-cooled Beam Dumps for High-Power Lasers
Stop! To Here and No Farther!
D76-071
The trend toward higher and higher laser power has continued for years – and not just in material processing. Not only the creation and transmission of laser power in the kW range but also its controlled blocking presents a challenge that should not be underestimated.
Gentec EO faces this challenge with its new BD series of water-cooled beam dumps.
There are two versions available (for up to 4 kW and 12 kW of laser power); both versions have an active aperture of 100 mm in diameter.
These beam dumps feature a very compact footprint because they are mechanically almost identical to the HP100A series of high-power detectors. Even the absorber material used is identical – for a damage threshold of up to 16 kW/cm².
To eliminate any disturbing, diffuse back reflections, these BD series beam dumps can also be equipped with a shielding tube that is optimized for the appropriate application.
Gentec’s BD series beam dumps: Simply connect the cooling water and … stop!

Beam Dumps
Beam Dumps
There are various situations in which one has a light beam, typically a laser beam, which is unwanted either temporarily or at all times, and therefore needs to be blocked – for example, for reasons of laser safety. For such purposes, one can use some kind of beam dump which safely absorbs the optical power. In contrast to a beam shutter, a beam dump cannot be deactivated – to release the beam again, the device needs to be removed.
Some typical situations in which beam dumps are required:
When some kind of pump laser sends a beam to another device (e.g., a titanium–sapphire laser or an OPO), on which one needs to temporarily work without the pump light (e.g. cleaning some mirrors), one may insert a beam dump between the devices (instead of turning off the pump laser).
One may need to permanently block beams resulting from parasitic reflections or transmissions. For example, even highly reflecting mirrors in a high-power laser may transmit a significant amount of optical power due to the high circulating intracavity power. Such parasitic beams may cause laser hazards or other problems, for example heating up the holders of some laser mirrors and thus causing thermally induced misalignment.
Some optical devices produce unwanted beams. For example, the non-diffracted beam of an acousto-optic deflector or one of the outputs of a polarizer in a variable optical attenuator may need to be dumped.
A kind of beam shutter for very high power levels can be realized with the combination of a beam dump and a movable mirror, which can be moved into the beam to send it to the dump.
Functions and Types of Beam Dumps
The perhaps most essential function of a beam dump is to avoid any of the light to be transmitted on its regular path. That purpose alone can be fulfilled with a simple beam block – for example, a metal part with a black coating (absorbing coating, e.g. anodized aluminum) and possibly some cooling fingers. Such parts are often home-made. Strongly suppressing scattered light needs somewhat more refined designs. In some cases, it is also important to strongly suppress any reflected and back-scattered light. For example, even a minimum fraction of scattered light from a kilowatt laser beam could be problematic in terms of laser safety. A simple beam stopper may then not be sufficient. Therefore, various kinds of beam traps have been developed which have somewhat more sophisticated setups. For example, there can be a cone-shaped black part into which the beam is sent. Most light which is reflected or scattered despite the absorbing coating reaches other parts of the black cone. Further, in front of the cone one may place some kind of cavity or tube which is also black inside. Optimized optical traps of such kinds send virtually no light back towards the source, at least when operated within the specified range of operation wavelengths.
Power Handling
Beam dumps for use with high-power laser beams have to dissipate substantial powers, which are turned into heat. For powers up to a few watts, it is normally sufficient to have some kind of cooling fingers attached to the absorber, which can release heat both by convection of air and by heat radiation. Note, however, that beam dumps can become rather hot during operation – sometimes reaching temperatures above 100 °C. Substantially increased powers (sometimes hundreds of watts) can be dissipated with fan-cooled devices. Possible disadvantages are, besides the somewhat higher cost, that possibly disturbing air flows and vibrations are caused, and a power supply is needed. For even higher powers (for example, several kilowatts), there are water-cooled beam dumps. Of course, their operation involves additional requirements, such as providing cooling water, safely avoiding any water leaks etc. In extreme cases, the absorption needs to be distributed over a larger volume. A possible solution is to absorb the light in a tank of water with added substances for obtaining an appropriate amount of absorption. Energetic pulses may damage a beam dumped even if the average power is within the allowed range! In any case, a high-power beam should not be sent into a beam dump with a too small beam radius, which would lead to excessive optical intensities. This is particularly the case for beams with high-energy pulses as obtained from Q-switched lasers. Such pulses may cause ablation or other kinds of degradation of the absorber material. Therefore, the specifications of beam dumps may contain limitations to the allowable fluence (in J/cm2) of pulses in addition to a limit for the average power.
Mounting
Permanently needed beam dumps should usually be rigidly fixed in the optical setup, e.g. using screws. It may also be helpful to obtain some heat flow from the beam dump into the base plate. In other cases, heating of the base plate may be unwanted (e.g. if thermal expansion courses misalignment of sensitive setups); one may then need to use a mount which minimizes thermal conduction. For other beam dumps, which are used only temporarily, it may be more convenient to use a magnetic mount, for example.

If you are harassed by lasers
“Mass hysteria is the rapid spread of illness symptoms for which there is no organic cause,” [Robert] Bartholomew [author of a book on the topic] told Newsweek. “It happens in normal, healthy people—it’s not just ‘all in their heads’ because they do experience symptoms.”
Jon Stone, a neurologist from the University of Edinburgh first consulted for
, agrees. “To consider this diagnostic possibility properly you have to strip away its negative connotations. The symptoms experienced in outbreaks of ‘mass hysteria’ are genuine and not faked or imaginary,” he told Newsweek.
Stone argues that the term “mass hysteria” itself sounds sensational and far-fetched. In reality, it is not as uncommon as you might think. He explains: “‘Mass hysteria’ is so laden with negativity, it badly distorts its own case. It suggests shrieking and raving individuals—not hard-working and normal people who mostly get functional disorders in everyday practice.”
A better, less stigmatizing term, says Stone, is “share functional disorder.” He defines the condition as
a genuinely experienced illness, “in which there is some disturbance of bodily functioning which conventional diagnostic techniques fail to register.”
Similarities
Differences
The study examined four possibilities to explain the symptoms: Infection, chemicals, psychological factors and microwave energy.
“Overall, directed pulsed RF energy … appears to be the most plausible mechanism in explaining these cases among those that the committee considered. … The committee cannot rule out other possible mechanisms and considers it likely that a multiplicity of factors explains some cases and the differences between others.”
The report says more investigation is required.
Persons who feel they have been targeted by mysterious enemies with directed energy devices may want to consider the case of the U.S. diplomats in Cuba afflicted by ” Havana syndrome .”In August 2017, reports came out that numerous U.S. diplomats serving in Cuba had been affected by mysterious “acoustic attacks.” Symptoms included hearing a buzzing sound, having headaches, hearing loss, balance issues and nausea. CBS News reported “mild traumatic brain injuries and possible damage to the central nervous system as a result of the attacks.”The question is whether Cuba targeted diplomats with an actual device, whether it was caused by pesticides or other untargeted source … or whether this may have been “mass hysteria.” According to a report in Newsweek There are interesting parallels with Havana syndrome and persons reporting unexplained laser harassment.In the Cuba case, around 25 U.S. diplomats, and 14 Canadian diplomats — persons who would be considered reliable and rational — reported hearing mysterious sounds and began having unusual, unexplained health problems. There have been numerous studies conducted by the U.S., Canada, Cuba, that as of early 2020 have not definitively established any cause. Experts are even divided on whether there is any physical change in the brains of the affected persons.In laser harassment cases, numerous persons — most of whom sound reliable and rational when we talk with them — report seeing lights and feeling heat from mysterious sources. Police, friends, family and medical experts trying to help them have been unable to find a cause. The only thing that is certain is the persons have genuine symptoms that are not faked or imaginary. To others, there may be no rational explanation — but the symptoms are genuinely experienced.One difference between the Cuba case and persons reporting unexplained laser harassment is that the latter are widely scattered. In Cuba there is the possibility of all the diplomats being exposed to the same causal factor (still unknown but possibly sound or pesticides). But persons reporting laser harassment are widely scattered across the U.S. and Canada. Perhaps there is a common cause within the environment.Also, the definition of mass psychogenic illness or “mass hysteria” almost always occurs in a relatively small group of people living or working together. This is true for the Cuba cases. But in the laser harassment cases, victims are again widely scattered and do not know, interact, or correspond (e.g. Internet) with each other.A study by the National Academies of Science concluded that the cause was likely microwave energy that may not have been deliberately targeting the diplomats in Cuba. According to an NBC News story quoting the study, “The committee felt that many of the distinctive and acute signs, symptoms and observations reported by (government) employees are consistent with the effects of directed, pulsed radio frequency (RF) energy. Studies published in the open literature more than a half-century ago and over the subsequent decades by Western and Soviet sources provide circumstantial support for this possible mechanism.”From the news story:LaserPointerSafety.com we are not aware of microwave directing devices that an ordinary citizen could purchase to cause problems for neighbors. It may be possible for a technically minded person to buy or modify devices and beam microwaves at other persons. But we are not experts in microwaves so we cannot give any more advice or opinion.
