Abstract

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.
