ABSTRACT:
There is disclosed herein a laser diode array including a plurality of laser diode bodies on a surface of a substrate. Each of the bodies has therein a semiconductor junction which is capable of generating light in the body when a suitable voltage is placed thereacross which junction extends to an end surface of the body. An end surface of each body is angled back under the body at an angle of 45.degree. with respect to the substrate surface and is reflective so that the light generated in the body is reflected by the end surface out of the body away from and substantially perpendicularly to the substrate. The bodies are arranged on the substrate with the angled end surfaces being adjacent to and facing each other so that the array provides a plurality of closely spaced, substantially parallel light beams emitted therefrom.
