摘要: Tm3+/Ho3+ co-doped LiGd(MoO4)2 (LGM) crystals were investigated as gain media for the Ho3+ laser around 2.0 μm. Polarized spectroscopic parameters of ions in calculated based on absorption spectra by Judd-Ofelt theory. Related fluorescence and decay curves measured analyzed with different concentrations, 5.4/1.4 4.6/0.6 at.%. Stimulated emission cross sections 5I7→5I8 transition derived according to Fuchtbauer-Ladenburg formula. End-pumped a pulsed diode at 795 nm, 2.05 μm slope efficiency 20% was realized c-cut crystal sample concentrations
