Abstract

We report a laser operation from a Fe:CdTe single crystal, pumped by 40-ns pulses of a 4.12-µm Fe:ZnSe laser. The maximum output energy of 5.8 mJ was produced at 5.4 µm with 30% absorbed energy slope efficiency. A record 2300-nm-wide smooth and continuous wavelength tunability over 4.5-6.8 µm range was demonstrated, being the longest wavelength tuning achieved for Fe-doped chalcogenide lasers. We also discuss the features of the oscillation spectra.

摘要

我们报道了一种基于Fe:CdTe单晶的激光运行情况，由波长为4.12 µm的Fe:ZnSe激光器的40 ns脉冲泵浦。在5.4 µm处产生了5.8 mJ的最大输出能量，吸收能量斜率效率为30%。在4.5 - 6.8 µm范围内实现了创纪录的2300 nm宽的平滑连续波长可调谐性，这是掺铁硫族化物激光器实现的最长波长调谐。我们还讨论了振荡光谱的特征。
