摘要：

Ultrafast optical pulses shorter than 20 fs with 400-mW average power at a 110-MHz repetition rate have been generated by a Cr4+:YAG laser with only double-chirped mirrors for dispersion compensation. The corresponding pulse spectrum has a peak intensity at 1450 mn and extends from 1310 to 1500 mn full width at half-maximum (FWHM). These pulses, which are believed to be the shortest generated to date from a Cr4+:YAG laser, are only four optical cycles within the FWHM intensity width. (C) 2002 Optical Society of America.
