Abstract:
1. Optical apparatus, comprising: a heat-sink; an elongated diode-laser bar having a slow-axis in the length direction of the diode-laser bar, a fast axis perpendicular to the slow-axis, and an emitting-axis perpendicular to the slow-axis and the fast axis, the diode-laser bar being in thermal communication with the heat-sink; first and second mounting bosses extending from a front face of the heat-sink, each thereof having a lateral face transverse to the slow axis of the diode-laser bar with the lateral faces spaced apart and facing each other in a direction parallel to the slow axis of the diode-laser bar; a lens assembly including an elongated cylindrical lens having an elongated mounting slab bonded thereto, the mounting slab having first and second lateral faces at each end thereof, the lens assembly being positioned so that the length of the cylindrical lens is aligned with the slow axis of the diode-laser bar and with the lateral faces of the mounting slab of the lens assembly attached by an adhesive to corresponding ones of the lateral faces of the mounting bosses; and wherein each of the mounting bosses has a hole extending therethrough from one face thereof to the lateral face thereof, wherein the length of the mounting slab of the lens assembly and the spacing between the lateral faces of the mounting bosses of the heat sink are selected such that there is a gap between each lateral face of the mounting slab and the corresponding lateral face of the mounting boss, and with the adhesive having been injected into the gaps via the corresponding holes in the mounting bosses.
