Laser Characteristics of Nd:S-FAP Crystal at 1.328 μm
The performance of low-threshold and high-efficiency Nd:S-FAP laser at 1.328 μm has been realized by using xenon flash lamp and tunable dye-laser (570~600 nm) pump respectively. The centre wavelength of frequeney-doubling laser is 664 nm and the linewidth is 1.3 nm. When the transmission of output reflector is 7%,for xenon flame pump the threshold energy is 240 mJ and the slope effeieney is 0.85%, while for tunable dye-laser pump, the threshold energy is 4.5 mJ and the slope efficiency is 38%. The laser characteristics, such as the emission spectrum, the polarization, the devergenee angle and the output energy in different cavity length were given.
