LASER SYSTEM WITH INCREASED LASER ENERGY WHILE MAINTAINING LOW LASER CLASSIFICATION

摘要

A laser system includes a laser module that generates a laser input beam. A first beam divergence structure is constructed and arranged to receive the laser input beam and to expand the laser input beam to a diverging beam. A second beam divergence structure is separate from and spaced from the first beam divergence structure. The second beam divergence structure is constructed and arranged to receive the diverging beam from the first beam divergence structure, creating an extended source, and to expand the diverging beam further into an output beam that illuminates an area. The second beam divergence structure defines a plane that a human eye cannot effectively see past so that the laser system can operate at higher power while maintaining a low laser classification.
