Abstract
Provided is a laser module that receives a first laser beam and outputs a second laser beam different from the first laser beam, the laser module including an optical system configured to modulate the first laser beam into the second laser beam and output the second laser beam, a first mirror disposed on an optical path of the first or second laser beam defined in the laser module, the first mirror reflecting the first laser beam to the optical system, a first sensor disposed adjacent to the first mirror and configured to sense the first laser beam incident to the first mirror, a second mirror disposed on the optical path to reflect the second laser beam to an outside of the laser module, and a first driver connected to the second mirror and configured to rotate the second mirror.
