摘要
The absorption spectrum of a new sort of crystal Nd:S-VAP was measured,which showed that Nd:S-VAP can be appropriately pumped at 583.0 and 809.0nm.By using tunable dye-laser(570.0-600.0nm)as pumping light,the performance of low threshold and high efficiency Nd:S-VAP laser has been realized.The characteristics of the output laser,such as 1.5nm linewidth,5 ns pulse width,almost total polarity,up to 50% conversion efficiency,down to 2mJ threshold energy and so on,were presented.Meanwhile,the prospect of Nd:S-VAP crystal for low threshold,high efficiency miniature laser was discussed.
