Abstract

Tunable laser action at 2.3 μm is of great interest for chemical detection and remote sensing. A laser at this wavelength based on the 3H4 - 3H5 Tm3+ transition has been demonstrated in several garnet1-2 and fluoride hosts3-4. In this paper we report on comparison of laser performance of 1.5 atomic % Tm:YLF and 1.5 atomic % Tm:YAG laser crystals. Output energies of over 1 mJ at 5 Hz have been achieved and slope efficiencies of 18% and 14% were measured relative to absorbed pump power for the YLF and YAG crystals respectively.

2.3 μm掺杂1.5%铥的YAG和YLF脉冲激光操作的比较

2.3 μm的可调谐激光作用在化学检测和遥感中引起了极大的兴趣。基于3H4 - 3H5 Tm3+跃迁的这个波长的激光已经在几种石榴石1-2和氟化物宿主3-4中被证实。本文报道了1.5%原子% Tm:YLF和1.5%原子% Tm:YAG激光晶体激光性能的比较。在5 Hz下，已经实现了超过1 mJ的输出能量，并且测量到YLF和YAG晶体相对于吸收泵浦功率的斜率效率分别为18%和14%。
