Abstract

Vortex beams, known for carrying orbital angular momentum (OAM), demonstrate significant potential across LiDAR, laser communications, high‐precision metrology, imaging, and quantum information. Generating vortex beam on demand is the basis and crucial for above implementations. Recently, solid‐state vortex laser in eye‐safe band have attracted considerable attention and been regarded as one of ideal sources for vortex beam generation, because of its advantages in high mode purity, mode selectivity, high output power, and locating in atmosphere window. In this perspective, we summarize the schemes of solid‐state vortex lasers in eye‐safe band, survey their potential in multi‐functional LiDAR systems, and discuss prospects for future development.

As one of the ideal vortex sources, solid‐state vortex laser at eye‐safe band has attracted considerable attention because of its potentials in multifunctional lidar. In this perspective, we summarize the schemes of eye‐safe vortex laser and discuss prospects for future development.
