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. The beam dumps are available at LASER COMPONENTS.
