摘要
报道准连续６０Ｗ激光二极管列阵侧面泵浦Ｎｄ：ＹＬＦ固体激光器的研究结果，当器件的运转重复频率为３０Ｈｚ时，得到４．４ｍＪ的１．０４７μｍ激光输出，光－光转换效率达到１８．３％，斜率效率达２４．４％。声光和电光调Ｑ，得到能量为２．２ｍＪ，脉宽分别为５０ｎｓ和３０ｎｓ的脉冲输出。探讨了静态输出的最佳耦合透过问题，将该器件的一些参数与Ｎｄ：ＹＡＧ进行了比较，指出了差别的成因。
We rePOrt Study on a Nd: YLF laser side-pumped by a quasi CW 60 W laserdiode-array. The laser provided 4. 4 mJ output energy at 1. 047 μm with repetition rate of 30 Hz. Which gives an optical efficiency of 18. 3% and slope efficiency of 24. 4 %.On acousto-ootic and electro-optic Q-switched operation, pulse energy of 2. 2 mJ was obtained with pulse widths of 50 us and 30 us respectively. The optimal output transmission at free running was revealed in experiments. Some parameters were compared with those of Nd: YAG lasers.
