A surface treatment laser beam delivery and tracking system is provided. The laser generates laser light along a original beam path at an energy level suitable for treating (e.g., eroding) a surface. An optical translator shifts the original beam path onto a resulting beam path. An optical angle adjuster...http://www.google.es/patents/US5980513?utm_source=gb-gplus-sharePatente US5980513 - Laser beam delivery and eye tracking system
