We report on a simple way to directly measure the Gouy phase shift of a strongly
focused laser beam. This is accomplished by using a recent technique, namely,
interferometric second-harmonic generation. We expect that this method will be of
interest in a wide range of research fields, from high-harmonic and attosecond
pulse generation to femtochemistry and nonlinear microscopy.
