A high power laser dump having defined laser beam introduction angles to the internal surface of a cylinder to maximize energy dispersion and absorption and having two zones formed of distinctive reflective and absorbing materials.
Changchun New Industries Optoelectronics Technology Co., Ltd. All. All; Title
A high powered beam dump apparatus and method for absorbing the power of a high power laser, while the beam is shuttered off from contact with a workpiece, comprises two principal features. A reflecting cone reflects and spreads the high power laser beam outwardly from the axis of a high power laser beam when the beam dump is positioned with ...
IR Beam Block Absorbs up to 80 W (CW) or 25 J/cm 2 (Pulsed) The LB1 (/M) Visible Beam Block absorbs CW visible laser beams. It is recommended for a maximum power of 10 W and is shipped pre-mounted on a 3" (75 mm) long, Ø1/2" post. The post is easily interchangeable with other Ø1/2" posts or Ø1" posts with 8-32 (M4) taps.
High Power Beam Dumps. These High Power Beam Dumps are able to trap beam outputs of up to 50W continuous wave (CW) lasers without the need for water-cooling. They are available in two aperture sizes: the 12mm aperture beam dump is able to handle the majority of beam sizes whilst the 52mm is able to handle expanded or more diffuse beams.
With air-cooling, lasers with power levels of up to 50 W. The beam dumps are suited for both cw and pulsed lasers from UV to IR and are available either with or without a stand. The high-power beam dumps from the Canadian manufacturer Gentec-eo have an aperture of 100 mm and can absorb up to 12 kW.
To avoid that painful fate, high-power laser fan [Brainiac75] undertook building a beam dump, which is a safe place to aim a laser beam in an experimental setup. His version has but a few simple ...

Beam Dumps safely terminate the beam of high-power lasers and high energy pulse lasers. The laser light is scattered and absorbed in the beam dump and converted into heat. Because the incident laser beam is scattered onto a conical surface, the light scatter back to the incident side can be greatly attenuated.
These devices are designed to safety absorb the "unused" part of a high power laser beam and dissipate the resulting heat, protecting nearby personnel and equipment. The BDFL500A-BB-50 is a fan-cooled Beam Dump for up to 500W. The BD5000W-BB-50 is a water-cooled Beam Dump for even higher power applications, up to 5kW.
High quality engineering design ensures smooth and reliable operation. Combined Shutter & Beam Dump The LS- series shutters are designed to absorb all the laser beam power thus eliminating the need for an additional beam dump and avoiding hazardous reflections. The laser beam is converted to heat and radiated from the shutter case. Shutters can ...

When the laser is not in use it is simply deflected elsewhere. However, for many lasers, this poses a safety hazard. Beam dumps are used for this purpose. In basic physical terms, the beam dump will absorb all the hazardous laser energy and dissipate it gradually and safely as heat. Laser Beam Dumps Watch on
