We describe an experiment on second-harmonic generation of a picosecond Nd:glass laser pulse with time predelay at intensities of up to 200 GW/cm{sup 2} and a wavelength of 1.053 {mu}m. Duration of the second-harmonic pulse was reduced to 0.6 ps from 1.5 ps width of the fundamental pulse at an optimum intensity of 50 GW/cm{sup 2}. The spatial profile of the laser beam is not degraded by self-focusing at an input intensity of {approximately}50 GW/cm{sup 2}. {copyright} {ital 1996 American Institute of Physics.}
