Abstract
Abstract A laser stud mount wherein one terminal connection is provided by the stud and the other by a strip line. One embodiment includes a light guide extending through the stem of the stud mount or along the surface of the stud base for monitoring the light output from the back end of the laser. The monitored light from the back end of the laser can be used to regulate the laser drive.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
A laser apparatus comprising: a metallic base; an externally threaded stem coupled to and extending from one side of said base, said stem having a bore therein along its axis; a heat sink coupled to and extending from another side of said base, said bore extending into said heat sink; an injection laser mounted on said heat sink and having a first terminal provided by said stem, base and heat sink; a strip line forming a second terminal for said injection laser; a body of electrically insulating material coupled to said base for securing said strip line; and a light guide consisting of a core region surrounded by a lower refractive index cladding region extending through the stem in said bore for receiving radiation from said laser and transmitting said radiation.
Claim 2
Dependent Claim
131 words
A laser apparatus comprising: a metallic base; an externally threaded stem coupled to and extending from one side of said base, said stem having a bore therein along its axis; a heat sink coupled to and extending from another side of said base, said bore extending into said heat sink; an injection laser mounted on said heat sink and having a first terminal provided by said stem, base and heat sink; a strip line forming a second terminal for said injection laser; a body of electrically insulating material coupled to said base for securing said strip line; and a light guide consisting of a core region surrounded by a lower refractive index cladding region extending through the stem in said bore for receiving radiation from said laser and transmitting said radiation.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1 wherein said light guide terminates at either of its ends in a convex lens element.
Claim 4
Dependent Claim
27 words
