Abstract

Ultrafast 2-μm range wavelength laser sources have plenty of applications [1], including sensing, spectroscopy, material processing and medical applications. One of the most popular methods for generating 2-μm optical frequency combs is to use synchronously pumped doubly resonant OPO (DROPO) operating at degeneracy [2]. It's known that degenerate DROPO is a naturally unstable system. However, with dither [3] or dither free locking [4], one can actively stabilize the DROPO at the degeneracy. In our experiment, we synchronously pump the DROPO by a home-built Yb:YAG Kerr-lens mode-locked thin-disk laser, emitting pulses at a wavelength of 1030 nm with a pulse duration of 270 fs, 27 W output power and 33 MHz repetition rate.
