Abstract
A holding apparatus including a fixture is described. The fixture of the holding apparatus, which receives a semiconductor laser bar for optical coating, includes a base and a pair of walls. The walls and the base have inner surfaces, and the walls have a top surface upon which the laser bar rests. An extending portion of the semiconductor laser bar fits in a cavity formed by the base and the walls. The facet edges of the laser bar do not extend horizontally beyond the walls of the fixture. A coating apparatus applies a coating to the facet edges of the laser bar without contacting any coating material on the extending portion.
