Abstract
Broadly tunable cw laser emission is demonstrated at room temperature in the 1.85 - 2.15 micrometers and 2.20 - 2.45 micrometers regions from Tm:YALO solid-state laser with 795 nm diode laser pumping. Also efficient cw laser operation at room temperature is demonstrated from the Er3+ in a garnet host at 2.8 microns, which is resonantly pumped with the 970 nm diode laser, resulting in a laser slope efficiency of 36%.
