| Abstract: | We report the high efficiency of solar pumped laser. The sunlight is concentrated by the concentrator system, which is composed by the Fresnel lens and the cone-channel condenser. The power density of sunlight concentrated by the concentrator system surpasses the lasing threshold for pumping laser. In the experiment, the sunlight concentrated is coupled into the conical chamber pumping Nd:YAG laser media. Laser output of 3.5 W has been achieved; the collect efficiency is 3.5 W/m2. The conversion efficiency is 1.0% from solar power into laser, and the slope efficiency is achieved 1.86%. |
