LASER DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/134966
Kind Code:
A1
Abstract:
A laser device (100-1) comprises a plurality of laser media (11) which generate laser beams having mutually different wavelengths, wherein the laser beams emitted from the plurality of laser media (11) are superimposed and combined by a superimposing lens (2) into one beam on a dispersion element (3). The dispersion element (3) is disposed at the position where the plurality of laser beams are superimposed into one beam by the superimposing lens (2). The dispersion element (3) returns some of the plurality of laser beams back toward the laser media (11) as a first laser beam, and causes some of the plurality of laser beams to be output as a second laser beam having a single optical axis.
