Abstract
Apparatus and methods are provided for a laser module with a base including stepped platforms with an offset relative to an adjacent platform, each stepped platform accommodating a laser source. The module has at least a first plurality of stepped platforms and a second plurality of stepped platforms. Each platform accommodates a laser source that is part of a plurality of laser sources. The plurality of laser sources is arranged in a single plane to have each laser source emit laser radiation in the same direction that is perpendicular to the single plane. Laser radiation generated by the laser sources associated with the first plurality of platforms is combined into a first combined beam of laser radiation and the laser radiation generated by the laser sources associated with the second plurality of platforms is combined into a second combined beam of laser radiation. The first and second combined beam of laser radiation are combined by an optical combiner and coupled into an optical fiber.
