Abstract

The possibility of high-intensity second harmonic formation with beam profile and pulse shape, which are similar to the Gaussian ones, under the cascading SHG with taking into account cubic nonlinear response of the medium is shown. The laser pulse with the doubled frequency has the intensity that is comparable with or greater than the intensity of the fundamental harmonic. The duration of the second harmonic pulse can be much smaller than the first harmonic pulse duration. We take into account the dispersion and diffraction of laser pulses and group velocity mismatching.
