Efficient control of automatic pulse compressor in chirped pulse amplification system

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.
