“…28) Numerous applications of scalar LG modes, covering several fields in physics, have been found: oam transfer to small particles, 29,30) cold atoms and particles trapping, [31][32][33][34][35] quantum information, 36) high resolution microscopy, 37,38) material processing, 39) etc. A large number of publications exist on the methods of formation of scalar LG modes both inside the cavity (active methods) 16,17,[40][41][42][43] and outside (passive methods), [44][45][46][47] where mode conversion to the required mode was achieved using holograms, spatial light modulators and diffractive optical elements.…”

Over the last twenty years, diode pumping of solid-state lasers has opened new prospects for the mode control and formation of Laguerre-Gaussian (LG) beams, enabling a large variety of applications. Experiments on scalar and vector LG modes selection in Nd 3þ -and Yb 3þ -doped ceramics and crystal lasers carried out at the Institute for Laser Science, Tokyo are reviewed. Selection of LG modes from low to high orders using intra-cavity elements, polarization-selective mirrors, or shaping the pump beam profile, is considered. Illustrations of record-high-order LG hollow modes, multiring modes with highly directional propagation properties, characteristics of cw and pulsed lasers with radially or azimuthally polarized beams of high polarization purity are presented. General solutions of the wave equation for the axi-symmetric electric field, which describe LG beams of various profiles, are proposed for data analysis. In parallel, a short review on LG modes selection studies carried out at other laboratories is given.

“…Moreover, multi-sector phase plates with specific patterns have been found to be remarkable candidates for maximizing the Shannon dimensionality D of an entanglement state by selective projective measurements [32,33] . There have been a multitude of studies regarding the manufacture of these phase plates, including molding techniques [34] , e-beam lithography [35] , e-beam deposition [36] , and direct laser writing by femtosecond laser pulses [37][38][39][40] . Utilizing femtosecond laser, Wang et al [39,40] fabricated microscale geometric phase optical elements from photoresist materials.…”

Light carrying orbital angular momentum (OAM) has a spatial distribution of intensity and phase, which attracts considerable interest regarding several potential applications in optical and quantum scenarios recently. Spiral phase plates are commonly used elements for generating and analyzing OAM states. In this study, we put forward a method of directly writing binary multi-sector phase plates using the femtosecond laser. These phase plates are engraved on fused silica, which could be applied in high-intensity regimes. Different binary multi-sector phase plates were generated with high quality, which were proved by the observation of their structures, accompanied by detecting the beam patterns with the Gaussian beams. The proposed method provides a crucial basis for the rapid manufacturing of phase plates using convenient equipment, which can generate the superposition OAM states and may lead to the capability of measuring the high-dimensional entanglement.

“…Using suitable optical devices, the Hermite-Gaussian (HG) beams can be converted into Laguerre-Gaussain (LG) modes. 15 The Laguerre-Gaussain (LG) modes exhibit characteristic orbital angular momentum. 16 The ring shape morphology of a beam with orbital angular momentum (OAM) is ideal for the observation of solar corona around the sun where the intensity of the beam is minimum at the center, in solar experiments, 17 astrophysical environment, 18 and earth's ionosphere.…”

Kinetic study of ion acoustic twisted waves with kappa distributed electrons

The kinetic theory of Landau damping of ion acoustic twisted modes is developed in the presence of orbital angular momentum of the helical (twisted) electric field in plasmas with kappa distributed electrons and Maxwellian ions. The perturbed distribution function and helical electric field are considered to be decomposed by Laguerre-Gaussian mode function defined in cylindrical geometry. The Vlasov-Poisson equation is obtained and solved analytically to obtain the weak damping rates of the ion acoustic twisted waves in a non-thermal plasma. The strong damping effects of ion acoustic twisted waves at low values of temperature ratio of electrons and ions are also obtained by using exact numerical method and illustrated graphically, where the weak damping wave theory fails to explain the phenomenon properly. The obtained results of Landau damping rates of the twisted ion acoustic wave are discussed at different values of azimuthal wave number and non-thermal parameter kappa for electrons.
