We realized a compact mid-IR room temperature operating Dy(3+):PbGa(2)S(4) laser, excited by a diode-pumped Nd:YAG laser at a wavelength of 1318 nm. The pumping laser was operating in pulsed mode with a pulse length of 4 ms and repetition rate of 20 Hz. Maximum pumping energy at a wavelength of 1318 nm was 15 mJ. Energy up to 90 μJ and mean output power of 1.8 mW was obtained at a wavelength of 4290 nm with a slope efficiency with respect to absorbed pumping energy better than 3%.
我们实现了一款紧凑的中红外室温工作的 Dy(3+)：PbGa(2)S(4)激光器，由波长为 1318nm 的二极管泵浦 Nd:YAG 激光器激发。抽运激光以脉冲模式工作，脉冲长度为 4ms，重复频率为 20Hz。在 1318nm 波长处，最大抽运能量为 15mJ。在 4290nm 波长处，获得了高达 90μJ 的能量和 1.8mW 的平均输出功率，相对于吸收的抽运能量，斜率效率优于 3%。
