 Blanking out of pulses in pulsed lasers for ldi mass spectrometers patent thumbnailBlanking out of pulses in pulsed lasers for ldi mass spectrometers
The invention relates to optically pumped and pulsed solid-state lasers which are used in mass spectrometers in particular for ionization by matrix-assisted laser desorption (maldi) and which operate at pulse frequencies of up to 10 kilohertz or even higher. The invention proposes that, instead of interrupting the clocked sequence of the laser operation, individual light pulses or groups of light pulses are blanked out so that subsequent light pulses do not have a higher energy density, in accordance with the requirements for ldi processes.
