PURPOSE: A hand piece device combined with a laser resonator is provided to remove a transmission loss of laser beams by not using an optical fiber which connects the laser resonator to a hand piece. CONSTITUTION: A laser resonator(20) generates laser beams. A lens(33) collects the laser beams transmitted from the resonator. A hand piece radiates the laser beams from the laser resonator to the outside. A connection member(40) includes joint arms(41,43) which connect the laser resonator to the hand piece to control an angle of the hand piece with regard to the laser resonator. |
