摘　　要：在放电泵浦ＸｅＣｌ准分子激光器上，对放大率Ｍ从１．８０到２０．５６共六种虚共焦非稳腔在放电电压为２０ｋＶ下的水平、竖直方向的束散角θ＿（１１Ｍ）．θ＿（⊥Ｍ）进行了系统的实验研究，并从理论上计算了本实验条件下的衍射极限ＤＬ＿（１１Ｍ）．ＤＬ＿（⊥Ｍ）。The output beam divergence angles θ_(11M). θ_(⊥M) of 6 kinds of positive-branch confocal and unstable resonators which magnification M ranges from 1 . 80 to 20.56 have been experimentally studied on discharge XeCl laser when discharge voltage equals to 20 kV.The diffraction limit DL_(11M).DL_(⊥M) versus M have been cal-culated under our experimental conditions.
