Abstract : The patent discloses a gallium arsenide laser array in which laser modules are mounted on a printed circuit support plate. Each module has a housing creating a cavity and shaped substantially as a pair of cones with opposing vertices. At the junction of the vertices there is a stack of gallium arsenide diode chips each of the chips being mounted on a heat sink with dielectric spaces therebetween. Each module has a spherical mirror positioned to reflect the laser beam through openings in the support plate. A lens array is mounted with support rods to the support plate with each lens of the array corresponding to a laser module.
