Use of mismatched grating pairs in chirped-pulse amplification systems

摘要

We demonstrate for the first time to our knowledge the use of mismatched grating pairs between the stretching and compression systems in a chirped-pulse amplification laser. Pulses as short as 57 fs are generated with 2000-lines/mm gratings in the compressor and 1200-lines/mm gratings in the stretcher. (C) 1998 Optical Society of America. [References: 6]
