Successful second harmonic generation from the radiation of Pr:YAP laser has been demonstrated. The flash-lamp pumped Pr:YAP laser was operated in Q-switched pulsed regime with 0.5 Hz repetition rate at room temperature. For Qswitching, electro-optical modulator based on LiNbO3 Pockels cell in quarter-wave configuration was employed. The pulses with an energy and length of 5 mJ and 50 ns were reached, respectively, at 747 nm wavelength. BBO crystal was used for second harmonic generation, and output pulses with the 30 uJ energy and 34 ns length were generated at 373.5 nm wavelength.
