Abstract

A cw Pr : Y Al O 3 microchip-laser operation in the near-IR spectral region is reported. A microchip resonator was formed by dielectric mirrors directly deposited on the Pr : Y Al O 3 crystal surfaces. For active medium pumping, a GaN laser diode providing up to 1 W of output power at ~448 nm was used. 139 mW of laser radiation at 747 nm wavelength has been extracted from the microchip-laser system. Slope efficiency related to the incident pumping power was ~25%.
