Abstract
Absorption sprctra and measurements and detailed analysis of Er:Tm:Ho:YLF absorption lines at 4 K were carried out. Laser induced fluorescence was utilized to study and modelling of multisite energy transfer dynamics of three different laser crystals namely, Cr Tm Ho in YAG, Tm Ho:YAG as well as Tm Ho: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.
