Publikováno v: The International Conference on Ultrafast Phenomena (UP) 2022.

We show that frequency resolved optical switching (FROSt) can be used to characterize high repetition rate laser sources. We characterize supercontinuum pulses extending from 1.2 µm to 1.8 µm up to 500 kHz.

Publikováno v: 2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC).

The development of mid-IR high repetition rate laser systems with a pulse duration in the few-cycle regime is driven by applications such as high harmonic generation [1,2] and multidimensional molecular spectroscopy [3]. Optical parametric chirped pu
