Continuous-wave self-mode-locked operation of a chromium-doped YAG laser pumped by a continuous-wave Nd:YAG laser at 20 °C is described. 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 μm. The TEM00 output power was as high as 360 mW. The output of this femtosecond source was tunable from 1.51 to 1.53 μm.
