Hermite-Gaussian-mode coherently composed states and deep learning based free-space optical communication link
Zilong Zhang, Suyi Zhao, Wei He +6
In laser-based free-space optical communication, besides OAM beams, Hermite-Gaussian (HG) modes or HG-mode coherently composed states (HG-MCCS) can also be adopted as the informati…

Self-healing and transformation characteristics of obstructed Hermite-Gaussian modes composed structured beams
Suyi Zhao, Zilong Zhang, Yuan Gao +3
The self-healing property of laser beams is of great interest. And a laser beam with spatial structures is also widely concerned due to its important applications in lots of areas.…

Transverse mode selective laser with gain regulation by a digital micromirror device
Zilong Zhang, Yuan Gao, Xin Wang +3
A transverse mode selective laser system with gain regulation by a digital micromirror device (DMD) is presented in this letter. The gain regulation in laser medium is adjusted by…
