摘　　要：根据ＡＢＣＤ定理，推出输出窗产生热透镜效应后束腰位置、光斑大小和发散角的变化，讨论了输出特性同输出功率的关系。From ABCD law, the change of the position of output laser beam waist, beam waist's size, and divergence angle of the fast axial flow CO_2 laser whose coupler has thermal effect are derived. And the relation is discussed between the output characteristics and the output power.

关 键 词：CO2激光器 热透镜效应 输出窗 输出功率
