Laser system and method for generating laser pulses

A laser system for generating laser pulses having a determined carrier-envelope-offset, CEO, the laser system comprising:

• a Cr-doped II-VI based laser oscillator system having a resonator cavity, wherein the laser oscillator system is configured to emit laser pulses from the resonator cavity having a peak power of at least 0.75 MW;
• a nonlinear optical element for spectrally broadening at least a part of the emitted laser pulses irradiated onto the nonlinear optical element to provide the laser pulses with octave-spanning spectral components;
• a frequency-doubling element for generating second harmonic spectral components of at least a part of the octave-spanning spectral components of the spectrally broadened laser pulses when irradiating the spectrally broadened laser pulses onto the frequency-doubling element, 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, wherein the nonlinear optical element for spectrally broadening and the frequency-doubling element are separate elements;
• and
• an f-2f-interferometry device for generating a beating signal of at least a part of the overlapping spectral components exiting the frequency-doubling element and interfering with each other at the f-2f-interferomtry device and for determining and/or controlling the CEO of the emitted laser pulses based on the beating signal.
