较全面地讨论了高峰值功率的ＬｉＦ：色心晶体调ＱＹＡＧ倍频激光器的稳定性。对谐振腔、聚光腔、闪光灯、倍频器、调Ｑ器件及发射激光谱线中的不稳定性进行了理论分析和实验测量，给出了相应的数据和图表。 A more comprehensive discussion of high peak power LiF: color-centered crystal QYAG frequency doubled laser stability. The theoretical analysis and experimental measurements of the instabilities in the resonator, condenser cavity, flash, frequency multiplier, Q-switched device and laser emission line were carried out, and the corresponding data and graphs were given.
