We present a fast and accurate method to calculate the vector-field distribution of a focused Gaussian beam. This method is applied to calculate the second harmonic that is generated by such a beam from a sample in the undepleted pump approximation. These calculations can be used to model second-harmonic imaging in an optical microscope with a wide aperture. © 2004 Optical Society of America.
