We report on spectroscopic and lasing properties of Pr:YAlO3 crystal down to cryogenic temperature. Fluorescence lifetime, polarization-resolved absorption and emission spectra, and laser characteristics in the green spectral range are described. Using 1-W InGaN laser-diode pumping together with microchip resonator geometry, 37 mW of continuous-wave output power at 547 nm wavelength at 80 K crystal temperature is reported. The corresponding oscillation threshold and slope efficiency related to absorbed pump power were 320 mW and 6.5 %, respectively.
