Abstract
Individually operable laser diodes in an array are associated with optical fibers for treatment of a material. Each laser diode has a generally Gaussian or similar profile. A guide block receives optical fiber terminal distal ends and enables irradiation of a surface for treatment with overlapping profiles. A control system controls individual laser diodes to achieve desired illumination profiles for a given process. The process is performed in a suitable environment which may include a vacuum system, controlled gaseous environment, or in a doping medium such as a surface coating or even a liquid. Optional relay optics interposed between the terminal distal ends and the treatment material allows distant relaying and reimaging. An optical isolator assembly may be interposed between the relay optics and the treatment material. The system and related methods allow direct irradiation from laser diodes to treat materials.
