Abstract
A laser apparatus includes six first laser devices that output respective blue laser beams for preliminary heating of an object, and a second laser device that outputs an infrared laser beam for main heating of the object. At least one of a relative positional relationship and each of respective first irradiation positions of the blue laser beams is changeable, the relative positional relationship being a relative positional relationship between the respective first irradiation positions of the six first laser beams in the object and a second irradiation position of the infrared laser beam in the object.
Claims14
A laser apparatus comprising:
- first light sources that output respective first laser beams to perform preliminary heating of respective first irradiation positions on an object;
- a second light source that outputs a second laser beam to perform main heating of a second irradiation position on the object;
- an input device that receives an input of an irradiation pattern from a user;
- and
- a controller, wherein
- the controller is configured to:
- control the second light source to output the second laser beam to the second irradiation position after a predetermined period of time has elapsed since outputting the first laser beams for the preliminary heating;
- and
