Linearizing nonlinear optics [PDF]
Conference on Lasers and Electro-Optics, 2016 In the framework of linear optics, light fields do not interact with each other in a medium. Yet, when their field amplitude becomes comparable to the electron binding energies of matter, the nonlinear motion of these electrons emits new dipole radiation

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 ...

Chirality in Nonlinear Optics and Optical Switching [PDF]
Molecular Crystals and Liquid Crystals, 1993 Chirality in molecular opto-electronics is limited sofar to the use of optically active liquid crystals and a number of optical phenomena are related to the helical macroscopic structure obtained by using one enantiomer, only. In this paper, the use of chirality in nonlinear optics and optical switching is demonstrated.

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
