Abstract

The optimal beam diameters ensuring the highest intensity in the focal point of a lens having chromatic aberration have been calculated. For large input beam diameters the pulse front distortion caused by the chromatic aberration, for small beam diameters the diffraction effects decrease the intensity in the focus. The highest intensity is obtained for intermediate beam diameters. It is shown that in case of optimal focusing the longitudinal chromatic aberration of the lens is about twice larger, than the depth of focus caused by diffraction effects. Nomograms are given for easy determination of the optimal beam diameters for different pulse shapes, pulse durations lens materials and wavelenghs.
