Radiation at a wavelength of 747 nm generated by flash-lamp pumped Pr:YAP laser

摘要

Successful room-temperature generation of the Pr:YAP laser radiation at a wavelength of 747 nm was demonstrated. Flash-lamp pumped Pr:YAP laser was operated in free-running pulsed regime at room temperature. Permanent laser action was reached by means of special UV color glass plate filter placed directly into the laser cavity. The maximum output energy and the pulse length reached were 102 mJ and 92 μs, respectively, at 121 J pumping (pumping flash-lamp pulse length was 110 μs). Stimulation emission excitation threshold was observed at 20 J.
