Design Considerations for a High Energy Front-End for a High Power OPCPA Laser Facility

摘要

We present the progress on the development of a high energy front-end capable of delivering pulses with energy over 7 J and bandwidth over 150 nm around the central wavelength of 910 nm. This system is composed of three stages: a seed generation using ps OPA techniques, a high repetition rate amplification stage using OPCPA with LBO and an high energy stage using OPCPA with KD*P. This front-end is characterized by high contrast, good compressibility and proper achromatic propagation system.
