Abstract

The latest efforts in performing high-power mid-IR optical refrigeration in Tm-doped crystals are reported. A Thuliumdoped fiber amplifier (TDFA) seeded by a mid-IR Continuous Wave Optical Parametric Oscillator (CW-OPO) and diodepumped at 793 nm is developed to obtain a high-power source in the mid-IR for laser cooling and RBL experiments. Using the TDFA, experiments are underway for implementing a Herriott cell geometry for laser cooling to low temperatures, as well as demonstrating the first mid-IR RBL in Tm and Ho-doped crystals.
