Abstract
In a method for the application of cuts, perforations and/or microlesions to biological material, such as cell agglomerates, individual cells or chromosomes, by means of laser pulses fed into a microscope, the laser pulses are focussed to a cross-section which is limited by diffraction phenomena, and the nth order diffraction maxima (n=1, 2, 3, . . . ) of the laser pulses are used to apply the cuts.
