Inventor(s) include Nithyanandan Kanagaraj; and Khushboo Soni.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "This disclosure presents a system and a method for generating a shaped optical beam through coherent combination of multiple laser channels. The system (100) is configured to generate a deterministic far-field beam shape through coherent combination of multiple laser channels under phase-noise conditions. A seed laser (101) generates a coherent optical beam that is divided by a beam splitter (102) into multiple optical channels, each optical channel including an amplitude modulator (103), a phase modulator (104), and an amplifier (105). The amplified optical channels are spatially arranged by an optical arrangement (106) into a hexagonal array of beams and propagated through a propagation region (107) to produce corresponding complex far-field contributions at a far-field target plane. A processor (108) stores calibrated complex far-field responses of the individual optical channels, assembles a propagation matrix, converts a user-defined target intensity pattern into a complex target field, and computes complex excitation coefficients in a single non-iterative analytic operation using a weighted, regularized Moore-Penrose pseudoinverse formulation incorporating modeled phase noise. A control interface (109) applies the computed coefficients to the channels such that coherent superposition of the modulated beams produces the shaped far-field optical beam without iterative optimization, feedback-based correction, or convergence loops."
