Design considerations for an interferometer for coherent combination of ultrashort laser pulses

摘要

Real-time interferometric method and system are proposed for monitoring thethermal, mechanical and optical fluctuations in laser amplification chains. Both the applied methodsand the used electronics are specially selected to allow building a real-time, high speed systemcapable to work in closed loop configuration. The system is developed to supervise and control thepiston error in the coherent combination of ultra-short and ultra-intense pulses.
