我们报道了一种有效的锁模二极管泵浦Nd:YLF激光器的谐振倍频技术，用于在光谱的绿色区域产生250 mW的连续波锁模输出。Nd:YLF激光器由3w激光二极管阵列泵浦，通过调频模式锁定，以225 MHz的重复频率产生持续时间为12 ps的650-mW脉冲输出。通过在外环增强腔中使用MgO:LiNbO(3)，该输出共振加倍。在523.5 nm处产生可用的250mw锁模输出，效率提高了一倍，达到56%。利用倍频输出同步泵浦连续波锁模罗丹明R6G染料激光器。染料激光器产生的脉冲持续时间约为1ps，输出功率为40mw。
We report an efficient technique of resonant frequency doubling of a mode-locked diode-pumped Nd:YLF laser for producing 250 mW of continuous-wave mode-locked output in the green region of the spectrum. The Nd:YLF laser, which was pumped by a 3-W laser-diode array, was mode locked by using frequency-modulation mode locking to produce 650-mW output in pulses of 12-ps duration at a repetition rate of 225 MHz. This output was resonantly doubled by using MgO:LiNbO(3) in an external ring enhancement cavity. Doubling efficiencies of as much as 56% were achieved to produce usable mode-locked output of 250 mW at 523.5 nm. The frequency-doubled output was used to pump synchronously a continuous-wave mode-locked Rhodamine R6G dye laser. The dye laser produced pulses of approximately 1-ps duration and an output power of 40 mW.
