Abstract: The present disclosure provides a method and to a device for quantitatively sensing the power fraction of a radiation background of a pulsed laser. The disclosure further relates to the use of a saturable element. The method includes modulating a measurement beam, which is emitted by the laser, by means of a saturable element in accordance with the fluence of the measurement beam, detecting, by means of a modulation beam power detector, the power of the measurement beam modulated by the saturable element, and determining the power fraction of the radiation background of the pulsed laser on the basis of the detected power of the measurement beam modulated by means of the saturable element.
