We present a mode-locked diamond Raman laser synchronously pumped by a mode-locked laser running at 532 nm and pulse duration 26 ps. The diamond laser generated up to 2.2 W of average power with output pulses of duration 21 ps at a yellow wavelength of 573 nm. The output pulse duration varied notably with small changes in cavity length and decreased to a minimum of 9 ps. The power and pulse duration behavior as a function of cavity length is explained well by a model that includes phonon dephasing and group velocity dispersion of the pump and Stokes fields.
我们展示了一种由工作在 532nm 且脉宽为 26ps 的锁模激光器同步泵浦的锁模金刚石拉曼激光器。该金刚石激光器在 573nm 的黄色波长下产生了高达 2.2W 的平均功率，输出脉冲持续时间为 21ps。输出脉冲持续时间随腔长的微小变化而显著变化，并减小到 9ps 的最小值。功率和脉冲持续时间随腔长的变化行为可以很好地用一个模型来解释，该模型包括声子退相和泵浦和斯托克斯场的群速度色散。
