摘　　要：给出高斯入射束反射时角位移直接计算式，适用于任意入射角和反射介质有吸收的情况。计算式在布儒斯特角上不存在发散困难。对于ｐ偏振和ｓ偏振均适用，只要令ｇ１＝ｎ１，ｇ２＝０计算所得即为ｓ偏振的角位移。Directly calculating expression of angular shift of a Gaussian beam reflected by absorbing medium interface is given, which can be applied to any incident angle and does not diverge at Brewster angle. This expression is symmetrical for both p and s polarization. Setting g 1=n 1 and g 2=0, we will obtain the angular shift of s polarization beam.
