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…
Generation of Chinese-characters-like modes with transverse mode locked lasers
Zilong Zhang, Yuan Gao, Changming Zhao
Spontaneous transverse mode locking to generate optical vortex arrays is already widely studied for the frequency degenerated transverse modes. While, the mode locking between tran…
