Cooled and uncooled single-channel deformable mirrors for industrial laser systems

A study was made of bimorph mirrors intended for industrial laser systems. The technical characteristics of cooled single-channel deformable mirrors were investigated in detail. Preliminary tests were made on uncooled bimorph mirrors in industrial laser systems based on a cw CO₂ laser with an output power in excess of 2 kW and on a pulsed copper vapour laser with an average power of 35 W.
