Abstract
Abstract A medical laser system for scanning a beam of laser light including an oscillating mirror that repeatedly scans a laser beam in a cyclical pattern, such as a circle or an ellipse, or in a zig-zag pattern within a defined boundary. The oscillating mirror can be included in a myringotomy instrument. Also, the oscillating mirror can be included in a joystick-controlled medical laser system, or in any other system where a cyclically scanned laser beam is useful.
