Generation of Perfect Vortex Beams with Complete Control over the Ring Radius and Ring Width
Photonics, 2023 We have experimentally created perfect vortex beams (PVBs) by Fourier transformation of Bessel–Gaussian vortex beams, which are generated by modulating the fundamental Gaussian beam with the spiral phase plates and the axicons, respectively. Although the

The breaking of transience inertio-gravity waves in a shear flow using the Gaussian beam approximation. [PDF]
, 2014 The propagation of transient inertio-gravity waves in a shear flow is examined using the Gaussian beam formulation. This formulation assumes Gaussian wavepackets in the spectral space and uses a second-order Taylor expansion of the phase of the wave ...
