Single-stage GaSe OPCPA delivering high-energy few-cycle pulses at 11 µm wavelength – INVITED [PDF]
EPJ Web of Conferences, 2023 The generation of sub-five optical cycle pulses centered at 11.2 µm wavelength with 50 µJ energy at a 1 kHz repetition rate is reported. A GaSe optical parametric chirped pulse amplifier (OPCPA) is driven by the residual 2.0 µm pump and 5 µm idler of a ...

Spectral meta-moments reveal hidden signatures of vortex pulses [PDF]
EPJ Web of Conferences, 2019 Ultrashort vortex pulses possess specific spatio-spectral signatures due to Gouy phase shift. Helical movement of anomalies around the phase singularity was found which is referred to as spectral Gouy rotation. The analysis of spectral moments allows for
