METHOD AND DEVICE FOR THE FAST PHASE EVALUATION, IN PARTICULAR OF MULTI-CYCLE PULSES OF LASER RADIATION

摘要

The aim of the present disclosure is to enable a fast CE phase evaluation of the laser pulses, in particular in real time, including for multi-cycle pulses. Said aim is achieved by providing a polarization gating stage (8) for changing the laser pulses (7) to be evaluated in the phase and subsequent phase evaluation stage (15) for measuring the phase position of the changed laser pulses. The descriptions in the present disclosure can be used for example in laser technology for producing and monitoring single-cycle pulses.
