| Abstract: | The laser diode array(LDA)end-pumped intra-cavity second harmonic generation 525 nm green laser was demonstrated by using 1 mm thick Yb∶YAG crystal. The doping concentration is 10 at.%. The temperature of Yb∶YAG crystal was controlled by thermo-electric cooler(TEC). The nonlinear optical crystal,LBO,at a type-I phase-matching direction of(θ,φ)=(90°,12.2°)was employed. With linear-type cavity,a CW output power of 244 mw at 525 nm green laser has been obtained when the incident power was 11.3 W. The optical conversion efficiency was 1.98%. |
