A method and apparatus for producing a laser diode assembly package is taught. Briefly stated, in a first embodiment, a housing having an access area at one end has a laser mounted therein. A collimator lens is placed at the other end of the housing and is movable along the optical axis of the laser output. This enables the collimator to be adjusted along the optical axis in order to produce an optimum amount of collimated light, with the housing and lens then be hermetically sealed with UV curable epoxy. In an alternate embodiment, the laser is mounted on a socket module which is then inserted into the housing.

Laser diode assembly

A cooling fin assembly for mounting on a semiconductor package that includes a plurality of pins adapted to be affixed to a surface on the package, and a cooling fin means having a thin walled cellular configuration with the cells defining elongated openings in side-by-side relation that extend through the fin means, the pins being seated in the cells of the fin means.
