| Abstract: | The analysis and the experiment of Nd:YVO4 crystal pumped by a fiber coupled diode array,type I critical phase matching LBO(LiB3O5)crystal intracavity frequency doubled,and high power CW red laser at output wavelength of 671nm is reported in this paper. By using a short folded cavity resonator,the thermal focal length of Nd:YVO4 crystal was calculated considering its thermal effect,and the parameters of laser cavity were selected by computer optimum design,with injection pump power of 26W,TEM00 mode red laser at 671nm of 6.8W is obtained at last,with the optical conversion efficiency up to 26%. |
