A laser device (), being configured for generating laser pulses by Ken lens based mode locking, comprises a laser resonator () with a plurality of resonator mirrors () spanning a resonator beam path (), a solid state gain medium () being arranged in the laser resonator (), a Kerr medium device () being arranged with a distance from the gain medium () in the laser resonator (), wherein the Kerr medium device () includes at least one Ken medium being arranged in a focal range of the resonator beam path and being configured for forming the laser pulses by the nonlinear Kerr effect, and a loss-modulation device () having a modulator medium, which is capable of modulating a power loss of the laser pulses generated in the laser resonator (), wherein the Kerr medium device () includes the modulator medium of the loss-modulation device () as the at least one Kerr medium having an optical non-linearity being adapted for both of creating the Kerr lens based mode-locking in the laser resonator and modulating the power loss in the laser resonator. Furthermore, a method of generating laser pulses by Kerr lens based mode locking is described, wherein a loss-modulation device () is used for both of introducing a Ken effect in the laser resonator () and modulating the power loss.
