Abstract Study on how to realize the operation of quasi-three-level system 946nm all-solid-state Nd:YAG laser at room temperature is reported?also the Means of emission of 473nm blue laser by lntracavity-doubling. 180nW output of 946nm infrared laser is obtained when pumped by a 2W diode with the slope Efficiency 13%. 12mW and 50mW output of 473nm blue laser are obtained using BBO and LBO doubling crystal with the slope efficiency 3% and 10%.

DreamLasers Nd∶YAG 946nm quasi-three-level laser system was studied theoretically. The way to realize the operation of 946nm all-solid-state infrared CW laser at room-temperature was presented. Through the optical-system specially designed by computer CAD system which can satisfy the requirement of focus, the maximum output power 120mW of 946nm infrared laser is obtained when pumped by a 2 W 808.5nm diode. At the same time, 10mW 473nm CW blue laser is obtained by intra-cavity doubling of BBO crystal. The slope efficiencies for 946nm infrared laser and 473nm blue laser are 10%and 2%, respectively.
