doi:10.3724/SP.J.1077.2008.01041

Abstract

Abstract: Nd:YSAG powders was prepared by using combustion method. After molding, calcining the Nd:YSAG green compact at 1750-1850℃ in H₂ atmosphere for 4-10h, the transparent Nd:YSAG ceramics were obtained. The optical properties of Nd:YSAG transparent ceramics were measured. The emission band of transparent Nd:YSAG ceramics is broadened and the fluorescence lifetime is prolonged as compared to Nd:YAG ceramics. Using LD as pumping source, and transparent Nd:YSAG ceramics as laser gain media, laser output is achieved. The maximum laser power is 0.36W and the slope efficient is 23.6%, the spectrum band of output laser is relatively broad.

Key words: Nd_x:Y_3-x(Sc_y,Al_2-y)A, laser ceramics, optical property, laser experiment
