In this contribution we present the external cavity enhancement of a 78MHz repetition rate 270 fs Yb-based fiber laser providing up to 20W average power. We measure a record high intra-cavity average circulating power of 13.7kW, which corresponds to more than 5 times the previously reported value.
We use low finesse Fabry-Perot cavities in series to generate frequency combs with large mode spacing by simultaneously maintaining high spectral bandwidth. The attenuation of laser modes closest to the pass band exceeds 70 dB relative to the modes centered within the pass band for a 5 GHz Fabry-Perot filtering a 250 MHz frequency comb.
An Yb-doped fiber laser and amplifier system is used together with an enhancement cavity for high harmonic generation for precision spectroscopy. Higher order harmonics can be produced in comparison to systems with Ti:sapphire lasers.
Generation of 130-fs pulse trains at 1560 nm with 1 GHz repetition rate is demonstrated by locking a fundamentally mode-locked 200 MHz repetition rate fiber laser to a high finesse (F=2100) external Fabry-Perot cavity.
The development of high finesse resonators for broadband frequency combs enabled the extension of the versatile frequency comb technique into the extreme ultraviolet with all its implications. We describe new developments in this field.
