Abstract

PURPOSE: To stably concentrate light independently of mechanical vibration by making a light guide path for irradiated light flexible when a solid body is highly purigied by relatively moving a melting zone.
CONSTITUTION: Light 2 emitted from a light emitting source 1 enters a flexible light guide path 4 and reaches the outlet of the path 4. The light 2 is centered by an optical system set at the emergent edge of the path 4, and it irradiates a solid body 3 to form a melting zone 31. At this time, by relatively moving the zone 31 in the arrow F direction while rotating the body 3 in the arrow R direction, with the movemtnt impurities are moved and segregated at an edge part. Several light beams may be irradiated separately.
