Laser beam device and laser beam hand piece

Abstract

The present invention relates to a laser beam device outputting a multi-spot laser beam, and a laser bean hand piece. The laser beam device, according to the present invention, comprises: a light source unit which generates and emits a single-spot laser beam having a first wavelength; a laser beam oscillation unit which outputs the first wavelength single-spot laser beam emitted from the light source unit as any one of a first wavelength multi-spot laser beam and a single-spot laser beam having a second wavelength, and then outputs any one of the outputted first wavelength multi-spot laser beam and second wavelength single-spot laser beam as a second wavelength multi-spot laser beam, and an amplification unit which amplifies the second wavelength multi-spot laser beam so that the output energy of the second wavelength multi-spot laser beam outputted from the laser beam oscillation unit is relatively high output energy.
