Abstract

Spectroscopic studies of Er:Tm:Ho:LiYF₄ (YLF) and Cr:Tm:Ho:Y₃Al₅O₁₂ (YAG) crystals were performed, with a detailed analysis of the absorption spectra of Er:Tm:Ho:YLF at 4 K. The dynamics of energy transfer Cr³⁺→Tm ³⁺→Ho³⁺ (in YAG) and Tm³⁺→Ho ³⁺ (in YAG and YLF) were studied utilizing laser-induced fluorescence. Pulsed, free-running laser performance of a freon-cooled Er:Tm:Ho:YLF at -10 and -50°C, at different current densities with maximum laser energies of 1.5 and 2.25 J/pulse, respectively, was performed.
