摘　　要：本文论述了利用β-BaB_2O_4晶体进行内腔连续波环形染料激光器倍频,获得了可调谐单频紫外相干辐射。在292nm附近,用3WAr^+激光(全谱线)泵浦,得到非线性转换系数～8.33×10^(-4)W^(-1)。通过改变相位匹配角,在288～302nm范围内输出连续可调谐紫外谐波。β-BaB_2O_4晶体角灵敏度～27cm^(-1)/mrad。The intracavity frequency-doubling in the CW tunable ring dye laser with β-BaB_2O_4 crystal to produce coherent tunable single frequency UV radiation is reported in this paper. Under 3W Ar laser (all spectral lines) pumping, the nonlinear conver- sion efficiency is ~8.33×10^(-4) W^(-1) at 292nm. The tuning range of the continuous tunable UV output is about 288~302nm by chang- ing the phase matching angle. The angular sensitivity of the β- BaB_2O_4 crystal is about 27cm^(-1)/mrad.
