Abstract

Influence of temperature on Pr:YAlO₃ laser behaviour in the near-infrared (747 nm), red (662 nm), orange (622 nm), and green (547 nm) spectral range is reported. To realize Pr:YAlO3 laser systems operating down to the cryogenic temperature, a microchip geometry formed by dielectric films directly deposited on the crystal facets has been proposed and employed. This geometry is particularly attractive due to its compact and rugged design. The best results were demonstrated for the 747 nm wavelength; more than 300 mW of output power with the slope efficiency over 55 % has been extracted from the cryogenically cooled Pr:YAlO₃ active material under 1-W InGaN diode pumping. In addition, the first diode-pumped Pr:YAlO3 orange laser is described, as we believe.
