【摘要】 成功研制了一台激光二极管列阵 (LDA)抽运的高稳定Nd∶YLF环形激光器。用输出激光强度负反馈控制谐振腔的增益 ,建立了准连续的～ 10 0 μs宽预激光状态 ,然后在此预激光基础上调Q。由于预激光模式与谐振腔固有模式一致并且具有一定强度 ,调Q脉冲的建立时间和幅度都很稳定。实验结果为 :输出调Q脉冲强度起伏不超过4 3% ,时间抖动小于± 4ns。更多还原

【Abstract】 A LDA pumped highly stable Nd∶YLF ring laser is developed. With an output laser intensity induced negative feedback control of resonator gain, a quasi-continuous prelase with duration of ～100 μs is established, then Q-switch during this prelase. Because the prelase mode is well matched to the resonator eigenmode and with certain intensity, the build up time and intensity of Q-switched pulse are very stable. Experimental results show that intensity instability of output Q-switched pulse doesn′t exceed 4.3%, and time jitter doesn′t exceed ±4 ns.更多还原
