Abstract

A laser diode subassembly is disclosed, in which dichroic reflectors are disposed sequentially one after another forming an array or stack, each reflector having a sequential array index. An array of laser diode emitters is provided, each emitter having a sequential array index. Individual reflectors of the array redirect laser sub-beams from individual laser diode emitters having same array indices, to propagate via dichroic reflectors having higher array indices, so as to form a combined optical beam. A common partial reflector may be used for the laser diode emitters instead of individual wavelength selective reflectors for each laser diode emitter.
