Abstract
Electro-optically Q-switched flash-lamp pumped Pr:YAP laser was demonstrated. Employing LiNbO3 Pockels cell in quarter-wave configuration giant pulses with an energy and length of 5 mJ and 50 ns, respectively, were obtained at 747 nm wavelength. Laser oscillator was operating at room temperature and with 0.5 Hz repetition rate. Considering that the Pr:YAP output radiation is naturally polarized, the necessity of polarizer presence inside resonator was also investigated.
