Multimode vector beam synthesis and rapid modulation via interferometric methods [PDF]
AIP AdvancesOptical interference techniques are widely regarded as an effective approach for generating vector beams. In this paper, we theoretically simulate the generation of multimode vector beams through the vortex beams interference. Then, in the experiment, we

Optics-to-THz conversion of vortex beams using nonlinear difference frequency generation [PDF]
Компьютерная оптика, 2019 In this paper, using a modified model of slowly varying amplitudes, a process of optics-to-THZ-conversion of vortex beams based on the nonlinear difference frequency generation in a medium with second-order susceptibility is considered.

Peculiar rotation of electron vortex beams [PDF]
Ultramicroscopy, 2015 Standard electron optics predicts Larmor image rotation in the magnetic lens field of a TEM. Introducing the possibility to produce electron vortex beams with quantized orbital angular momentum brought up the question of their rotational dynamics in the presence of a magnetic field. Recently, it has been shown that electron vortex beams can be prepared

Conical Emission Induced by the Filamentation of Femtosecond Vortex Beams in Water
Applied Sciences, 2023 Conical emission is a typical nonlinear phenomenon that occurs during the filamentation of femtosecond laser pulses in transparent media. In this work, the conical emission induced by two kinds of typical vortex beams (i.e., Laguerre–Gaussian (LG) and ...
