AbstractIn order to solve the problem of low segregation coefficient of Nd3+ ions in YAG crystal, Sc3+ ions are used to replace some Al3+ ions in YAG, so that the YAG cell becomes bigger, thereby the segregation coefficient of Nd3+ ion increase. In this paper, the spectra and laser characteristics of Nd:YSAG single crystal are studied. The (1.5 at.%) Nd3+ :Y3Sc2Al3O12 (YSAG) laser crystal is grown by Czochralski method, and X-ray rocking curve shows that the crystal quality is good. The concentration of ions in Nd:YSAG is measured by an electronic probe. The segregation coefficient of N3+ ion is calculated to be 0.35, which is approximately twice as much as that of Nd3+ in YAG. The absorption and emission spectra are measured, which indicates that it can be pumped by an 808 nm-laser diode (LD). The strongest emission from the transition F-4(3/2) -> I-4(11/2) of Nd:YSAG peaks at 1059 nm with an emission cross section of 1.03 x 10(19) cm(2), and the lifetime of F-4(3/2) is about 253 mu s, which indicates that Nd:YSAG has roughly an efficiency equal to that of Nd:YAG, but the laser upper level lifetime is longer than that of Nd:YAG, which is more favorable for Q- switched laser operation. The 808 nm-LD is used to pump Nd:YSAG rod of 2 mm x 2 mm x 6 mm, the laser operation with a threshold of 0.85 W and a maximum output power of 1.1 W is realized: the laser slope efficiency is 21.1%, and the optical conversion efficiency is 18.3%. All of the above results show that Nd: YSAG single crystal is a good solid state laser material, which is more favorable for Q- switched laser operation.
