Abstract

The growth, structure, spectra, laser preperties and some physical properties of a new laser crystal Nd:Sr5(PO4)3F (Nd:SFAP) were studied in order to search and evaluate the applications of the crystal to laser. The Nd:SFAP single crystals were successfully grown by Czochralski method and the laser experiment of the crystal crystal pumped by laser diode (LD) was demonstrated. The properties of as-grown crystal were measured by advanced equipments. Experimental results showed that Effective distribution coeffcient Keff of Nd was 0.52. π polarization light with wavelength of 806nm was the best pumping light. The fluorescence lifetime of 2 at % Nd:SFAP crystal was 175 μs. The pumping threshold of Nd:SFAP laser was 15mW and its slope efficiency was 31.8%. From the investigation we can draw a conchusion: the Nd:SFAP crystal is an ideal laser mateiral for lower power lasers, but it isn't suited to be applied to higher power lasers.
