“…The TM 01 mode with a mode purity of 98.2% was reached. The purity maintained steadily while the pump power was changing [30]. In 2019, Wei et al reported a solid laser which had a low threshold.…”

Structured light fields carrying orbital angular momentum (OAM) have been widely studied, and a variety of applications have been found. The exploration of the generation of the structured light beams with higher purity, order, and efficiency has become an inevitable trend. In early years, structured light beams are normally generated with the extra-cavity methods, as it is simpler in principle. However, the intra-cavity generation of the structured light has a better beam purity and higher light conversion efficiency. Here, the current advance in the production of structured light directly from lasers based on spatial light modulators (SLMs), metasurfaces, and microrings is reviewed.

“…This work was extended to demonstrate arbitrary lateral shapes by multibeam superpositions, tunable twisted light, dynamic fiber lasers, and the use of a dual cavity to excite two spatial modes which could be combined to form arbitrary vector beams from a digital laser . Additions of acousto‐optic modulators have likewise allowed dynamic selection of various structured light beams . To date, no laser based on intracavity DMD technology has been demonstrated, yet this hold promise for faster, wavelength invariant and polarization independent mode control.…”

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.

“…Applications of such kind of device include mode-locked fiber lasers [21] and Q-switched fiber lasers [22]. In terms of mode conversion, it has also been adopted for generating cylinder beams and optical vortex beams [23]- [27]. It should be noted that fast mode-switching capability of the above-mentioned fiber laser based on AIFG has not been fully studied and the output powers of these fiber lasers are relatively low (less than several tens of milliwatts).…”
