ABSTRACT:
Apparatus and method for the precision treatment of a material using a semiconductor diode for generating a plurality of laser light beams, optical fibers coupled to the diode for transmitting and combining the light beams, and a scanner for scanning the combined light beams onto the material to be treated. Also, channels micromachined onto a fixture are provided for supporting the fibers in optimum alignment with the diode. Also provided are a camera and a thermal image capturing system for generating optical and thermal images of the material. An image processing unit is provided for receiving and processing the image to generate and transmit control signals to a diode controller to control intensity and timing of the light beams, and to a controller of the scanner to control positioning of the scanner to deflect the laser beam over the material as desired.
