Special Issue Information

Dear Colleagues,

The unique helical phase distribution of the vortex laser field is widely used in many advanced technological fields. In nanoparticles, the orbital angular momentum of the vortex laser can manipulate nanoparticles and living cells, making a breakthrough contribution to biomedicine. In information transmission, vortex beams have functions like ultra-high-density optical data storage, imaging, and metrology, and have good prospects in free space communication. With the deepening of research on quantum optics, the development of quantum communication, computing, measurement, and sensing also relies on vortex lasers. There are many types of vortex lasers, such as semiconductor lasers, fiber lasers, and all-solid-state lasers, which can output different types of vortex lasers in different wavebands. The performance improvement and application exploration of vortex lasers involve multiple disciplines, like optics, materials science, electronics, communication engineering, information science, and biology.

This Special Issue aims to publish selected articles on vortex lasers and their applications. Possible topics of interest include, but are not limited to:

  • Vortex laser design;
  • Design and simulation of vortex light transmission model;
  • Vortex optical communication technology;
  • Future development of vortex lasers;
  • Applications of vortex lasers.

In this paper, the evolution of the beam from the double Hermite–Gaussian beam superposition state to the double Laguerre–Gaussian beam superposition state is realized based on the astigmatism conversion. Firstly, the tunable output of the double Hermite–Gaussian mode superposition state is realized by adjusting the off-axis pumping distance of the crystal. On this basis, an astigmatic mode converter is added to the back end of the resonant cavity output mirror. By utilizing it, the evolution from the double Hermite–Gaussian mode superposition state to the specific double Laguerre–Gaussian mode superposition state is realized. The evolution process of the double mode superposition state based on the astigmatic mode is analyzed theoretically. The light field change of the evolution process is demonstrated experimentally.
