| Abstract: | The absorption spectrum of a new crystal Nd:S-FAP(Nd:Sr5(PO4)3F)was measured,which showed that it had broad effective band and two strong absorption peaks at 575.0nm and 804.5nm.By using tunable dye-laser,a absorption coefficient of 20 cm-1 at 575.0 nm was measured.Using atunable dye-laser(575.0nm)as pump source,we have realized the performance of total polarized laserat 1.059μm. The lowest threshold energy is 2.5mJ and the highest slope efficiency is 49%. The wavelength of frequency-doubling laser is 0.5925μm and the linewidth is 1.0nm. |
