摘要: 利用优化的腔设计,使谐振腔中增益介质中有大的模体积，并在高功率泵浦下具有高的热稳定性；采用热补偿环形径向侧面泵浦模块技术进行了连续Nd:YAG主动声光锁模的实验研究, 利用自行设计的锁相环反馈电路，获得输出功率10 W的稳定的锁模脉冲输出。Abstract: An actively mode-locked Nd:YAG laser with an optimized resonator was demonstrated which can provide with large mode volume in the active material and high stability against thermal lensing fluctuations. By using a compact pump module which utilizes a radial array of close-coupled diode laser arrays for efficient direct side pumping of the Nd:YAG rod, as well as, a phase-lock loop circuit, 10 W continuous-wave mode-locked stable pulses were obtained.
