Abstract

In this paper, we demonstrate the efficient 1.3 um dual-wavelength operation of LD end-pumped Nd:YAG ceramic laser. With a plano-concave cavity, a maximum continuous-wave dual-wavelength output power of 5.92 W is obtained under an incident pump power of 20.5 W, giving a slope efficiency of 30.3% and an optical-optical conversion efficiency of 29.0%. With Co(2+):LaMgAl(11)O(19) crystal as the saturable absorber, the passively Q-switched dual-wavelength operation is achieved for the first time to our knowledge. The maximum passively Q-switched average output power is 226 mW, the minimum pulse width is 15 ns, and the highest pulse repetition rate is 133 kHz.

摘要

在本文中，我们展示了激光二极管端面泵浦的Nd:YAG陶瓷激光器高效的1.3微米双波长运转。采用平凹腔，在20.5瓦的入射泵浦功率下，获得了5.92瓦的最大连续波双波长输出功率，斜率效率为30.3%，光光转换效率为29.0%。据我们所知，首次采用Co(2+):LaMgAl(11)O(19)晶体作为可饱和吸收体实现了被动调Q双波长运转。被动调Q的最大平均输出功率为226毫瓦，最小脉冲宽度为15纳秒，最高脉冲重复频率为133千赫兹。
