The absorption spectrum of a sort of new crystal Nd:S-VAP was measured,which showed that Nd:S-VAP is appropriately pumped at 583.0 nm and 809.0 nm. By using tunable dye-laser as pumping light, the performance of low threshold and high efficiency Nd:S-VAP laser has been realized. Up to 50% slop efficiency and down to 2 mJ threshold energy were obtained. The center wavelength of frequency-doubling laser is 536.0 nm and the emission linewidth is 1.4 nm. In addition, the prospect application of Nd:S-VAP crystal for low threshold, high efficiency miniature laser pumped with LD was disscussed.
