Abstract
A laser beam reflection system for applying a laser beam to an area to be treated. The laser beam reflection system has a hollow head housing, first reflecting mirror means disposed in the rotary head housing and adapted to deflect the laser beam introduced into the rotary head housing away from the axis, second reflecting mirror means disposed in the rotary head housing and adapted to reflect the laser beam coming from the first reflecting mirror means to such a direction as to traverse the axis, and third reflecting mirror means disposed in the head housing movably in the direction traversing the axis and adapted to reflect and focus onto the area the laser beam coming from the second reflecting mirror means. The laser beam reflection system of the invention can be used for welding, surface treatment, heat treatment, cutting of various materials, and a light source of laser communication systems.
