Laser notching apparatus

A laser notching apparatus comprising:

• a laser irradiation unit comprising a first laser irradiating a first beam, a second laser irradiating a second beam, and an optical member which forms paths of the first beam and the second beam;
• and
• a control unit configured to move a reflective mirror of the laser irradiation unit along a notching line of an electrode,
• wherein the optical member forms the path of the first beam and the path of the second beam such that a first spot of the first beam and a second spot of the second beam are arranged apart from each other by a first distance on the notching line, and a size of the first spot is larger than a size of the second spot, and the control unit moves the reflective mirror of the laser irradiation unit such that a spot of the second beam follows a moving trajectory of a spot of the preceding first beam.
