Resumen
The one-dimensional, high-order Hermite?Gaussian (HG0n) laser beams can be easily converted into vortex Laguerre?Gaussian (LGpl) beams carrying orbital angular momentum (OAM), and with the scaling of output power and the narrowing of pulse width, the applications of HG0n laser beams have been expanded from original cutting-edge scientific scenarios to optical measurement, material processing, aerospace communication, and many other fields.
