Patent ID: 7226218

Claim:
A method for forming a laser module having a laser optically coupled with an optical fiber via a collimating lens and a focusing lens, the method comprising the steps of: (a) mounting said laser in a laser housing so that its laser light output is directed toward a laser housing wall opening in a laser housing wall of the laser housing; (b) providing a lens-fiber housing having a focusing lens installed in a first end thereof and a light-receiving input end of the fiber disposed in a bore at a second end thereof, wherein the focusing lens and input end of the fiber form a collimator, and wherein the focusing lens is passively pre-aligned with the fiber via the lens-fiber housing; (c) mounting the lens-fiber housing from the outside of said laser housing to the laser housing wall to receive collimated light transmitted from inside the laser housing through said laser housing wall opening; and (d) actively aligning the collimating lens in the laser housing, between the laser and the laser housing wall opening, to determine an aligned position and securing the collimating lens in the laser housing at said aligned position.
