Abstract

We show how to exploit the high quadratic nonlinear coefficient of the organic crystal N-(4-nitrophenyl)-L-prolinol for generation and parametric mixing of ultrashort pulses by use of tilted-pulse techniques. The effective crystal length for subpicosecond operation is shown to be enhanced from tens of micrometers to tens of millimeters. Efficient frequency doubling of 100-fs pulses is predicted in walk-off-compensated geometries with peak intensities of a few megawatts per square centimeter.
