Abstract

Abstract: In this work, a cryogenic cooled, longitudinal diode-pumped D y 2 + :CaF2 laser was investigated for the first time. The temperature dependence of the spectroscopy and the laser properties of D y 2 + :CaF2 are presented. The tested D y 2 + :CaF2 crystal was a longitudinal pump in a near-IR region (926 nm) by laser diode radiation. The maximal mean output power and slope efficiency at 78 K during the pulse regime of the laser were 57.5 mW and 7%, respectively. Furthermore, the CW regime was successfully tested and a maximum output power of 0.37 W was obtained for the absorbed pumping power 5.7 W. The emission laser wavelength was 2367 nm.
