The invention relates to a laser system for the ionization of a sample by matrix-assisted laser desorption in mass spectrometric analysis. The invention consists in providing an adjustable laser system which, in one setting, generates a single intensity peak on the sample and, in another setting, a multiplicity of intensity peaks, with the half-width, intensity, spatial arrangement and/or degree of spatial modulation of the single intensity peak and/or the intensity peaks being adjustable. |
