Abstract :
Summary form only given. Precise mechanical control of grating pulse compressor in chirped pulse amplification system is of paramount importance in a wide range of application of high intensity femtosecond lasers, because the accurate pulse characterization and the reduced alignment tasks for attaining a tailored ultrashort pulse are desired. We have proposed a femtosecond automatic pulse compressor for use in a chirped pulse amplifier using stepping motors and PZT driven actuators controlled by PC. Introducing the new parameters that are measured by SPIDER, a further improvement is obtainable.
