Abstract :
Summary form only given. This paper describes auto-aligned femtosecond lasers controlled by genetic algorithms (GAs). We made a system based on precise and compact positioning actuators with /spl mu/m resolution. The initial experiments for CW oscillation for a Ti:sapphire laser obtained 1.66 times higher output power with 3 hours, compared to a hill-top-climbing method which corresponds to manual alignment procedure. We have made and demonstrated an auto-alignment femtosecond laser system including a SESAM mirror. This system can be optimized by GA utilizing signals from a two-photon-absorption detector.
