描述了用308 nm XeCl准分子激光双侧面对称泵浦之形腔染料激光器，重点探讨了这种激光器的输出光束质量改善问题，实验发现这种双侧面对称泵浦较传统的横向泵浦，光束质量有较好的改善，对于2×10-3 mol/l浓度的coumarin 460染料甲醇溶液，在波长460 nm处，实验得到11.7％的能量转换效率。

This paper described a dye laser with zig zag cavity pumped symmetrically from two sides by 308 nm XeCl excimer laser.Improvment of the output beam was investigated and the experiments show that the quality of the output beam by using symmetrical pump from two sides is better than that by using ordinarily transversal pump. For dye coumarin 460 dissolved in methanol with 2×10 -3 mol/l concentration, energy transference of η =11.7% was obtained at the wavelength of 460 nm.
