Abstract
A high efficient diode-pumped Tm:GdVO4 microchip laser is demonstrated. Output power of 310 mW at 1917 nm with slope efficiency of 22% is produced when pumped by 2 W of power at 802 nm. Unpolarized fluorescence spectra near 1800 nm pumped by laser diode are measured. In addition, the most important upconversion fluorescence from 1D2 to 3F4 and 3H6 levels is discussed.
