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.
