Low-noise generation of UV dispersive waves at 100 kHz
None:
We experimentally demonstrate efficient generation of tunable UV pulses at 100 kHz via resonant dispersive wave emission in an argon-filled hollow capillary. We measure a few µJ UV pulse energies both in linear and circular polarization. The dispersive wave emission is driven by 1030 nm 28 fs pulses generated by a ytterbium laser temporally compressed in a single-stage multipass cell. The UV source has a short-term (over a 1 s time scale) relative intensity noise of 0.58%. Coupled with the high repetition rate and the versatile polarization state, this makes it a relevant source for statistically demanding spectroscopy.

Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...
