Air and Water-cooled Beam Dumps are designed to block CW or a pulsed laser beam.
Beam Dump 10BD01 is designed to block a CW or a pulsed laser beam. It can be used on beams of up to 50 Watts in the wavelength range from 0.1 to 30 m. The design is such, that, even if the non-reflective coating is damaged by high intensity pulses, there's no backward reflection.
Water-cooled Beam Dump 10BDWC01-2. Beam Dump 10BDWC01 blocks a CW or a pulsed laser beam. It is mainly intended for beams 2 inch wide. Water absorbs much energy. So, the beam dump is best suited for laser beams of over 50 Watts. The wavelength range is from 0.1 to 30 m. Even if the non-reflective coating is damaged by high intensity pulses, the laser beam is not reflected back into your optical scheme. Laser beam dump mounts on an M6 hole on its back.
