The laser characteristics of a novel high efficiency and low threshold laser crystal Nb: S-FAP were reported. The laser characteristics of pulsed and continuous Nd: S-FAP laser were studied by using dye laser and LD as pumping source. The pumping threshold of the dye-laser-pumped Nb: S-FAP laser is 2.5 mJ and the ramp efficiency is 49%. The LD pump-pumped Nd: FAP laser has a pump value of 9 mW and a ramp efficiency of 37.3% The pump threshold of the Nd: S-FAP / KTP intracavity frequency doubling laser is 12.1 mW and the light-to-light conversion efficiency is 9.5%.
