英文摘要	A method and apparatus are provided for mounting a laser diode in an existing TO-5 structure within a cylindrical heat sink so that the laser beam can be focused, aimed and collimated in a mechanically repeatable manner in about 45 seconds. The basis for so doing lies in the use of an alignment apparatus to align the beam of a laser diode within its TO-5 heat sink structure with a lens that has been placed within a second heat sink, and thereby to form an aimed laser optic system (ALOS). The apparatus is constructed using processes that leave several compressive forces acting within itself, whereby the structure is constrained to adopt configurations that are essentially identical upon each installation of a laser diode. An interference fit of the TO-5 heat sink flange against the second heat sink provides an additional degree of heat sinking, thereby permitting the diode to be operated at temperatures of up to 130 deg. F. without damage.
