ABSTRACT:
A heating device comprises a laser oscillator which emits a laser beam, a reflector which guides the laser beam from the laser oscillator to an object a support pole for supporting the reflector to pivotally oscillate about an axis substantially perpendicular to an axis of the object, and a pair of electromagnets for oscillating the reflector between a maximum tilted position in one direction and a maximum tilted position in an opposite direction and for stopping the reflector at both maximum tilted positions for a predetermined period. The laser beam which is incident on the reflector reciprocally scans the object in the axial direction of the predetermined range thereof by the oscillation of the reflector.
