Large aperture composite adaptive optics for laser applications is investigated in cooperation of Institute of Plasma Physic, Dpt. of Instrumentation and Control Engineering FME CTU and 5M Ltd.We are exploring oportunity of a large-size high-power-laser deformable-mirror production using a lightweight bimorph actuated structure with a composite core. In order to produce a sufficiently large operational free aperture we are developing new technologies for production of flexible core, bimorph actuator and deformable mirror reflector.Full simulation of a deformable-mirrors structure was prepared and validated by complex testing.A deformable mirror actuation and a response of a complicated structure are investigated for an accurate control of the adaptive optics.An original adaptive optics control system and a bimorph deformable mirror driver were developed.A large-size 300 mm composite-core bimorph deformable mirror was simulated and optimized, fabrication of a prototype is carried on.
