摘要： Disclosed is a laser array beam combiner. A laser array emits a laser beam bundle that is incident on and transmits through a fast-axis collimator to form a one-dimensional quasi-parallel beam bundle A. The first quasi-parallel beam bundle is then incident on and transmits through the cylindrical lens to form a two-dimensional quasi-parallel beam bundle B. The quasi-parallel beam bundle B is then incident on and transmits through the dispersion unit and returns along the original path to the cylindrical lens, and then transmits through the cylindrical lens to be focused onto a common image point. Thus, the wavelengths of various light emitting spots of the laser array can be locked and the individual array beams can be automatically synthesized as a single-point beam bundle, improving the brightness of the laser array.

摘要： Laser diodes formed on a common substrate with layers of suitable thickness and refractive indices produce output beams that are coherently coupled. A phase mask can be situated to produce phase differences in one or more of the output beams to produce a common wavefront phase. The phase-corrected beams propagate with reduced angular divergence than conventional lasers that are not coherently coupled, and the coherently coupled laser diodes can provide higher beam brightness, enhanced beam parameter product, and superior power coupled into doped fibers in fiber lasers.
