采用紧凑的直腔设计和精确的膜系设计,实现了LD侧面泵浦1110 nm Nd：GGG和腔内倍频的555 nm激光。当泵浦功率为168 W时,得到了25.5 W的1110 nm连续激光输出。在10 kHz的声光调Q情况下,应用II类非临界相位匹配LiB3O5(LBO)倍频晶体,得到了最大输出功率为3.1 W的555 nm倍频光输出,光-光转换效率为1.8%,相应的脉冲宽度为176 ns,在水平和竖直方向上的M2因子分别为19.6和21.3。

A high- power diode- side- pumped 1 110 nm Nd:GGG laser and a laser at 555 nm based on intracavity frequency doubling of 1 110 nm laser were demonstrated for the first time. A simple straight cavity scheme was employed to achieve a compact configuration and all the coatings were designed specially. A 25.5 W 1 110 nm laser continuous wave output was achieved under the incident pump power of 168 W. A LiB3O5 (LBO)crystal was used for second harmonic generation of the laser. As a result, at the pump power of 168 W, the maximum power of the frequency- doubled output at 555 nm was found to be 3.1 W with a pulse repetition rate of 10 kHz, corresponding to an optical- to- optical conversion efficiency of about 1.8%. And the pulse width of 555 nm wave was 176 ns. The M2 factors are measured to be 19.6 and 21.3 in the horizontal and vertical directions, respectively.
