Abstract
Absorption spectra measurements and detailed analysis of Er:Tm:Ho:YLF absorption lines at 4 K were carried out. Laser induced fluorescence was utilized to study energy transfer dynamics of three different laser crystals namely, CrTmHo in YAG, TmHo : YAG as well as TmHo : YLF. Pulsed, free running laser performance of a freon-cooled Er:Tm:Ho:YLF laser at -10°C and -50°C at different current densities with maximum laser energies of 1.5 J/pulse and 2.25 J/pulse, respectively were obtained.
