Abstract
A method for controlling the emission frequency of a laser comprises: recording a first spectrum by passing a laser light emitted by the laser through a sample onto a detector, the detector being connected to a multichannel analyzer which assigns pulses detected by the detector to a channel; determining a first channel to which the maximum of a first signal in the first spectrum has been assigned; determining a second channel to which the maximum of a second signal in the first spectrum has been assigned; recording a second spectrum in analog fashion like the first spectrum; determining whether the maximum of the first signal in the second spectrum has been assigned to the first channel and whether the maximum of the second signal in the second spectrum has been assigned to the second channel; adjusting the operating temperature of the laser in the event of deviations determined in the previous step.
