摘　　要：A continuous-wave Nd:KGd(WO4)2 single-longitudinal-mode laser is demonstrated with Fabry-Perot etalons in a simple linear cavity.The thermal lens effect is dramatically lowered by propagating the laser beam along the‘athermal’direction inside the laser crystal,which is very beneficial to removing the heat generated in the mode selection process.The maximum single-longitudinal-mode output power obtained is 64.8 mW at incident pump power of 4.7 W,corresponding to an optical conversion efficiency of 1.3%and a slope efficiency of 1.7%.
