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