Abstract
A compact laser diode pumped, actively -switched, and mode-locked Raman laser is demonstrated. With the incident pump power of 9.11 W and pulse repetition frequency of 15 kHz, a maximum average output power of 1.003 W at 1178 nm was obtained and the corresponding conversion efficiency was 11%. A perfect stable mode-locking operation with the modulation depth of 100% was obtained and the corresponding mode-locking pulse width was less than 207 ps. The actively -switched and mode-locked Raman laser was theoretically analyzed and calculations were conducted using the fluctuation rate equation model.
