Problem: various spectroscopic applications require a high average and peak power laser source delivering ultrashort pulses at few megahertz repetition rates. To date, commercially available systems can only partially fulfill these requirements at the expense of other output parameters.
Solution: thin-disk oscillators can provide an excellent solution for high-demanding applications, as they combine all the qualities in a relatively simple tabletop system. Fortunately, our group focuses on developing these types of lasers, and we are excited about our recent results and future prospects!
Motivation: it has been recently demonstrated that thin-disk oscillators have great potential for peak and average powers scaling [1]. The current state-of-the-art system can deliver 200 W, 120 fs long pulses at a 14 MHz repetition rate, resulting in 110 MW output peak power [2]. Supplemented by extra cavity pulse compression and CEP stabilization, few-cycle pulses can be generated! In particular, these pulses are of great interest for high-harmonics generation and the subsequent high-precision XUV frequency comb spectroscopy [3], where no tunable narrow-band lasers exist so far.
