Abstract: A Faraday rotator includes two magnet sub-assemblies assemblies spaced apart and aligned with each other with a gap therebetween. Each magnet sub-assembly includes a central magnet magnetized in direction parallel to the gap. The central magnet is sandwiched between two end magnets magnetized in a direction perpendicular to the gap. A magneto-optic crystal is located in the gap between the central magnets.

Abstract: The present disclosure relates to a method and to a device (1) by which a train (2, 2) of short laser pulses of a mode-coupled laser (3) is compensated with respect to the carrier envelope offset frequency of the individual lines contained in the associated frequency comb. The aim of the disclosure is to determine the carrier envelope offset frequency and to utilize said frequency to operate an acousto-optical frequency shifter (13). In said shifter, the uncompensated train of temporally equidistantly short laser pulses is diffracted in a first order such that the individual lines of the frequency comb are shifted by the carrier envelope offset frequency. The resulting compensated train of short laser pulses has a frequency comb, the individual lines of which are integral multiples of the repetition frequency of the individual light pulses in the train of short laser pulses.
