Abstract
The generation of femtosecond optical pulses centered at similar to 620 nm
directly from an all-solid-state laser oscillator is reported. Red pulses w
ith pulse widths of the order of 170 fs were obtained with 24-mW average po
wer at an 81-MHz repetition rate. They were achieved by intracavity frequen
cy doubling of a mode-locked Cr4+:forsterite laser with a 1-mm-thick beta -
BaB2O4 crystal. The process of laser mode locking was modified by surface c
oating the doubling crystal. (C) 2001 Optical Society of America
