Title:
LASER BEAM DEVICE AND LASER BEAM HAND PIECE
Document Type and Number:
WIPO Patent Application WO/2017/188778
Kind Code:
A1
Abstract:
The present invention relates to a laser beam device outputting a multi-spot laser beam, and a laser beam 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 a relatively high output energy.
