  • Method and device for carrier envelope phase stabilisation
    Patent number: 8462825
    Abstract: A method of stabilizing a carrier envelope phase of laser pulses generated with a laser device, comprising the steps of generating laser pulses with a seed laser unit, amplifying the laser pulses with an amplifier unit, generating an amplifier output signal derived from the laser pulses amplified with the amplifier unit, and controlling the carrier envelope phase of the laser pulses with an amplifier loop based on the amplifier output signal, wherein the controlling step comprises a step of adjusting an optical path of the amplifier unit in dependence on the amplifier output signal, wherein the adjusting step comprises introducing a dispersive material into the optical path of the amplifier unit. Furthermore, a stabilizing device for stabilizing a carrier envelope phase of laser pulses and a laser device including at least one stabilizing device are described.
