Continuous-wave self-mode-locked operation of a chromium-doped YAG las
er pumped by a continuous-wave Nd:YAG laser at 20-degrees-C is describ
ed. We used both regenerative initiation and continuous-wave self-mode
-locking techniques to generate nearly transform-limited pulses of 120
-fs (FWHM) duration at 1.52 mum. The TEM00 output power was as high as
360 mW. The output of this femtosecond source was tunable from 1.51 t
o 1.53 mum.
