“…Usually a sign for the m value indicates the non-degenerate modes and degenerate modes appear without a sign. 19) The intensity distributions of nondegenerate LG pAEm modes have circularly symmetric annular shapes: LG 0AEm modes have a single ring profile with the dark central area that expands as jmj increases. The degenerate hollow LG 0m modes will have 2m lobes in the azimuthal direction, which form petal-like structures.…”

“…19,26,27,88) For example, the LG 01 mode appears with two lobes. An incoherent superposition of two LG 01 beams, rotated by 90 one with respect to another, can display a circularly symmetric intensity distribution.…”

“…[7][8][9][10][11][12][13][14][15][16][17][18] Generally, intra-cavity elements for mode selection are introduced in the laser resonator in order to produce low losses for a specific desired mode and high losses for other modes. Mode selection techniques based on the usage of intra-cavity apertures, phase plates, gradient mirrors and on different resonator configurations were reviewed by Oron et al 19) The number of reports on mode selection in solid-state lasers has dramatically increased during the last two decades with the advent of diode-laser pumped solid-state lasers (DPSSLs). [20][21][22] Most of the present DPSSLs are lasers operating near the wavelength las ¼ 1 m, based on Nd 3þ -and Yb 3þ -doped glass, crystals or ceramics active 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.

“…Spiral phase plates are widely employed as mode selectors, in active cavities [2], as etalons [3] and in free space [4]; in the rotation of microparticles [5] and nanomechanical elements [6,7]; in microscopy [8]; in astronomy [9]; and in tests of quantum mechanics [10].…”

“…Thus, ray matrix analyses of mirrors and lenses, of optical resonator stability, and of fiber waveguiding can be found in several optics textbooks [11,12]. There is also a practical need for a spiral phase plate ray matrix, so that ray optics can be extended to systems that integrate spiral phase plates with standard optical components [2,9], without necessitating recourse to the more complicated wave-optical diffraction theory. A description of the effect of a spiral phase plate on light rays has been presented earlier [13], highlighting the role of orbital angular momentum transfer, but without reference to a ray transfer matrix.…”

Structured light is derived from the ability to tailor light, usually referring to the spatial control of its amplitude, phase, and polarization. Although a venerable topic that dates back to the very first laser designs, structuring light at the source has seen an explosion in activity over the past decade, fuelled by a modern toolkit that exploits the versatility of diffractive structures, liquid crystals, metasurfaces/metamaterials, and exotic laser geometries, as well as a myriad of applications that range from imaging, microscopy, and laser material processing to optical communication. Here, the recent progress in creating and controlling structured light is reviewed, with particular emphasis on structuring light at the source: structured light lasers. The various design approaches, including pump shaping, cavity geometries, and the use of custom intracavity optical elements, implemented in a variety of lasers from microchip solutions to high‐power fibers are covered in a tutorial style. The history and latest developments in the field are reviewed, elucidating the various structured light patterns that have been created from lasers, including orbital angular momentum and vector states of light. Finally, the present challenges and limitations are highlighted, along with comments on likely future trends.
