Abstract: An apparatus includes at least one multijunction diode laser situated to emit a plurality of beams along respective mutually parallel propagation axes, each beam having an associated mutually parallel slow axes and associated collinear fast axes, a fast axis collimator situated to receive and collimate the plurality of beams along the corresponding fast axes so as to produce corresponding fast axis collimated beams that propagate along associated non-parallel axes, and a reflector situated to receive the plurality of fast axis collimated beams and to reflect the beams so that the reflected fast axis collimated beams propagate along substantially parallel axes.

Abstract: Laser module including a meniscus collimating lens. In some embodiments, a monolithic material having an index of at least 2.0 provides a concave lens surface proximal to an emission surface of the laser and a convex lens surface distal from the emission surface. In some embodiments, a perimeter of the collimating lens has a face-flat that may be disposed directly against a reference surface while the concave lens surface is separated from the emission surface. The meniscus lens may advantageously provide reduced angle of ray incidence and require lower asphericity relative to a plano-convex collimating lens.
