Abstract: A method generates laser pulses by varying a Q-factor in a resonator. The method includes generating the laser pulses by controlling an optical modulator with a control signal for switching over between a first operating state of the optical modulator for generating a first Q-factor in the resonator and a second operating state of the optical modulator for generating a second Q-factor in the resonator. The second Q-factor is different than the first Q-factor. In order to generate a sequence of the laser pulses in which first laser pulses alternate with second laser pulses different than the first laser pulses, the optical modulator is controlled differently in each case alternately with the control signal for generating a respective first laser pulse, of the first laser pulses, and a respective second laser pulse, of the second laser pulses.

Abstract: A laser clock signal generator for controlling a laser beam generator to generate pulse laser radiation is provided. The laser clock signal generator includes a clock signal specification input arranged to receive an external clock specification signal, a basic clock signal generator configured to generate a basic clock signal based on the external clock specification signal and output the basic lock signal at a clock signal output to the laser beam generator, and a controller configured to control the basic clock generator, for example, to be synchronized with the external clock specification signal. The laser clock signal generator also includes an overclocking protector arranged between the basic clock generator and the clock signal output.

Abstract: A laser for generating pulsed laser radiation. An element is arranged in the resonator to generate laser radiation having the first wavelength by frequency conversion of the primary radiation. The resonator is switchable into a first state in which it is open to the primary radiation, and a second state in which it is closed to the primary radiation, and is open to laser radiation of the first wavelength in both states. A control unit switches the resonator from the first to the second state so that the primary radiation begins to oscillate and the pulse generation by frequency conversion begins, switches the resonator from the second to the first state, whereby primary radiation is coupled out from the resonator. It is possible to set the duration between both steps and/or the coupling-out behavior of the resonator to adjust the pulse duration via the control unit.
