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.
