    摘要： An embodiment relates to a laser system (20) for generating laser pulses having a determined carrier-envelope-offset, CEO. The laser system (20) comprises a Crdoped II-VI based laser oscillator system (22) having a resonator cavity (112), wherein the laser oscillator system (22) is adapted to emit laser pulses (10) from the resonator cavity (112) having a peak power of at least 0,75 MW. The laser system further comprises a nonlinear optical element (26) for spectrally broadening at least a part of the emitted laser pulses (10) irradiated onto the nonlinear optical element to provide the laser pulses (10) with octave-spanning spectral components, and a frequency-doubling element (34) for generating second harmonic spectral components of at least a part of the octave-spanning spectral components of the spectrally broadened laser pulses (10) when irradiating the spectrally broadened laser pulses (10) onto the frequency-doubling element (34), such that a part of the second harmonic spectral components spectrally overlap with a part of the remaining octave-spanning spectral components of the laser pulses (10). In addition, the laser system comprises a f-2f-interferometry device (40) for generating a beating signal of at least a part of the overlapping spectral components exiting the frequency-doubling element (34) and interfering with each other at the f-2f-interferomtry device and for determining and/or controlling the CEO of the emitted laser pulses (10) based on the beating signal. Another embodiment relates to a method for generating laser pulses (10) having a determined carrier-envelope-offset.
