Název v původním jazyce

Power-scaled Laser-diode Pumped 747 nm Pr:YAlO3 Laser in Microchip Resonator Arrangement

Popis výsledku v původním jazyce

The power-scaled Pr:YAlO3 continuous-wave laser operation at 747 nm has been demonstrated. Microchip geometry realized by resonator mirrors directly deposited as a dielectric films on the crystal facets has been employed. Using both-side 1-W InGaN laser-diode pumping, continuous wave output power of 490 mW was reached in nearly diffraction limited beam. The corresponding slope efficiency related to the absorbed pump power was 45 %. We believe that this is the highest output power and slope efficiency ever reported from the Pr:YAlO3 crystal at room temperature.
