Abstract

Room-temperature lasing at 2.1-μm has been demonstrated in Ho:Lu3Al5O12 with a slope efficiency of 82% and a threshold energy of 4.4 mJ. A maximum absorbed energy of 17 mJ yielded 10 mJ of laser output energy. To simulate diode-pumping experiments, a tunable Co:MgF2 laser operating at 1.878 μm was used to achieve lasing on 5I7 → 5I8 transitions.
