In the present work we report on spectroscopic properties and laser results of GaN laser diode pumped Pr:YAlO3 crystal at room temperature. The polarization-resolved absorption and emission spectra have been recorded and the decay time of the 3P0 manifold has been measured. Three samples with different Pr3+-ion concentrations in YAP matrix have been tested and compared. The best results were achieved for 0.6 at. % Pr3+-ion doping: an output power of 91 mW at 746.9-nm wavelength with a maximum slope efficiency of 45% with respect to the absorbed power.
