Abstract :
Spectroscopic properties and laser results of GaN-diode pumped Pr, Ce:YAlO3 crystal at room temperature are reported. The polarization-resolved absorption and emission spectra have been recorded and the decay time of 3P0 manifold has been measured. The concentration of Pr3+ and Ce3+ ions in YAlO3 (YAP) matrix were 0.6 and 0.1 at. %, respectively. Output power of 30 mW at 747 nm wavelength with slope efficiency of 7 % with respect to the absorbed power has been demonstrated.
