对LD端面泵浦Nd:YAG/Gr~(4+):YAG热键合调Q激光器进行了实验研究.采用φ3×12mm晶体,端面镀膜方式在晶体两端直接构成平-平谐振腔.采用LD端面泵浦方式,分别研究了该激光器的脉冲重复频率、平均输出功率和脉冲宽度等参数随泵浦功率变化的输出特性,随着泵浦功率的增加,脉冲重复率和输出功率与泵浦功率呈线性增加,而脉冲宽度则有被压缩的趋势.当LD泵浦功率为6W时,热键合调Q激光器获得波长为1064nm、脉宽为5.3ns、平均功率为690mW的被动调Q激光脉冲输出.其光-光转换效率为11.5%,光束发散角为3.1mrad.实验结果表明,热键合激光器热效应好、可靠性高、输出光束质量高,是一种性能良好的新型一体化调Q固体激光器. |

LD pumped thermally bonded Nd:YAG/Cr~(4+):YAG Q-switched laser experiment was studied. A 3×12 mm thermally bonded crystal was used and a parallel resonator could be obtained by directly coating dielectric film on both sides. With LD ending pump,the characters of laser output such as pulse repeat rate,average output power and pulse duration were discussed. With the pump power increasing,the average output power and pulse repeat rate were linearly increased,the pulse duration trended to be compressed. With 6 W pump power,the thermally bonded laser could obtain a Q-switched 1 064 nm laser pulse with 5.3 ns pulse duration and 690 mW output power. The light-light efficiency of Q-switched laser was about 11.5%,the beam divergence angle was 3.1 mrad. Experiment shows that the thermally bonded laser has good thermal effect,high reliability,and high quality of light beam. It is a new type of Q-switched solid laser with good performance. |
