Coherent beam combining of cylindrical vector beams for power scaling.
Optics Letters, 2023Coherent beam combining (CBC) of cylindrical vector beams (CVBs) based on an active phase controller is proposed and demonstrated. Experimentally, two pieces of spatially variant wave plates (S-wave plate) were employed as vector mode convertors for two ...

Dynamic beam lasers based on coherent beam combining
Fiber Lasers XIX: Technology and Systems, 2022Steering a laser beam is a well-studied method for attaining welds with better quality in reducing pores, spatters, and other defects. However, the steering frequency, the possible shapes, and the total power are limited.

Combining module based on coherent polarization beam combining
Applied Optics, 2017A multiaperture receiver with a phased array is an effective approach to overcome the effect of the random optical disturbance in coherent free-space laser communications, in which one of the key technologies is how to efficiently combine the multiple laser beams received by the phased array antenna.

Coherent beam combining based on the SPGD algorithm with a momentum term
Optik, 2020The stochastic parallel gradient descent with a momentum term (named MomSPGD) algorithm is innovatively presented and applied for coherent beam combining to substitute for the traditional SPGD algorithm. The feasibility of coherent synthesis system using

Vortex Coherent Beam Combining
Laser Congress 2021 (ASSL,LAC), 2021We propose Coherent Beam Combining with vortex wavefront to create an effective optical trap. More than 50 dB barrier height (wall to center irradiance ratio) for 127-hexagonal lattice was shown in numerical model.
