激光二极管泵浦Nd:NaY(WO4)2晶体的激光性能
LASER PROPERTIES OF Nd:NaY(WO4)2 CRYSTAL PUMPED BY A LASER DIODE
摘要
Abstract
Sodium yttrium tungstate crystals doped with Nd3+ [Nd:NaY(WO4)2, Nd:NYW] with an average size of φ25 mm×50 mmwere grown by the Czochralski method. The absorption spectrum of the Nd:NYW crystals was measured. The absorption peaks of the crystals at 804, 752 nm and 586 nm were intensive and wide, making them propitious for the laser diode (LD) pump. The laser characteristics of the crystal were studied using the xenon flash lamp and LD pump as the pumping sources, respectively. The output energy of the laser rod is 36.9 mJ when the input energy of the xenon flash lamp is 11.7 J. When the LD pumping power is 1 W, and with an output power of 273 mW for a wavelength of 1.06 μm laser, the laser rod has a laser threshold of 160 mW, an optical-optical transfer efficiency of 27.3%, and a slope efficiency of 34%.关键词
