A laser apparatus provided with an aiming beam using a method for the injection of both laser light and aiming beam forming light in an optic fiber will be described herein. More specifically, the present disclosure describes a method, an injection module and a laser apparatus designed to inject laser light into the core and aiming beam forming light into the cladding of the optic fiber.

Laser diode apparatus provided with an aiming beam and injection method therefor

An improved laser diode assembly and a method of making such an assembly are provided. The assembly has a substrate wherein channels are formed to receive laser diodes. The channels have an inwardly tapering shape, with a first side wall generally perpendicular to the front surface of the substrate and a second side wall at an angle with the first side wall. A metallic coating is provided over the front surface and the side walls of the channels, with a break at the bottom of the channels. Laser diode bars are mounted along the first side wall of each channel, and a conductive body such as a metallic wire is wedged between the laser diode bar and the opposite tilted side wall. The laser diode bars and wires are held in place by a solder layer. Advantageously, this assembly can be manufactured with less stringent fabrication tolerances than with known laser diode arrays.
