Abstract

We report a narrow-linewidth, tunable, gain-switched Cr:ZnSe laser operating between 2255 and 2455 nm. The spectral width of the laser was reduced from 125 nm to 0.3 nm by using injection seeding. Seeding was achieved with a second tunable CW Cr:ZnSe laser. The output wavelength was varied by tuning the wavelength of the seed laser. The seeded oscillator produced as high as 157 µJ pulses with 598 µJ incident pump pulse energy at a repetition rate of 1 kHz. The slope efficiency was determined to be 26%.

摘要

我们报告了一种窄线宽、可调谐、增益开关的 Cr:ZnSe 激光器，其工作波长在 2255nm 到 2455nm 之间。通过注入种子实现了光谱宽度从 125nm 减小到 0.3nm，种子激光采用第二台可调谐连续波 Cr:ZnSe 激光器实现。通过调谐种子激光的波长来改变输出波长。在 1kHz 的重复率下，该种子振荡器产生了高达 157µJ 的脉冲，入射泵浦脉冲能量为 598µJ。斜率效率被确定为 26%。
