Abstract

A growing number of applications can benefit from carrier envelope offset frequency (f_CEO) stabilized sources with high average output power (hundreds of watts), i.e. pulse energies of several tens of µJ and high repetition rates in the multi-MHz regime. One important example is XUV frequency metrology based on extra or intra-cavity high-harmonic generation. So far, however, no stabilized frequency comb with >100 W of average power has been demonstrated and the frequency comb with the highest average power (80 W) is currently based on a fiber amplifier system [1]. Among possible laser technologies with multi-100-W performance, SESAM-modelocked thin-disk lasers (TDLs) are particularly promising: they achieve the highest average output power (275 W) and pulse energy (80 µJ) of any oscillator, directly from a low-noise compact system without further external amplification [2].
