  • Laser system
    Patent number: 10050408
    Abstract: A laser system may include a plurality of laser apparatuses, a beam delivery device configured to bundle pulse laser beams emitted from respective laser apparatuses of the plurality of laser apparatuses to emit a bundled laser beam, and a controller configured to control operated laser apparatuses of the plurality of laser apparatuses such that, at a change in a number representing how many laser apparatuses are operated, a beam parameter of the bundled laser beam emitted from the beam delivery device approaches a beam parameter of the bundled laser beam emitted before the change.
    Type: Grant
    Filed: December 14, 2016
    Date of Patent: August 14, 2018

  • Laser system
    Patent number: 9966721
    Abstract: The laser system may include first and second laser apparatuses and a beam delivery device. The first laser apparatus may be provided so as to emit a first laser beam to the beam delivery device in a first direction. The second laser apparatus may be provided so as to emit a second laser beam to the beam delivery device in a direction substantially parallel to the first direction. The beam delivery device may be configured to bundle the first and second laser beams and to emit the first and second laser beams from the beam delivery device to a beam delivery direction different from the first direction.

  • LASER SYSTEM AND LASER ANNEALING APPARATUS
    Publication number: 20180019141
    Abstract: A laser system may serve as a light source of a laser annealing apparatus that irradiates a workpiece with a pulse laser beam. The laser system may include: a laser apparatus configured to generate the pulse laser beam; a time-domain pulse waveform changing apparatus configured to change time-domain pulse waveform of the pulse laser beam; and a controller configured to receive at least one parameter for generating the time-domain pulse waveform from the laser annealing apparatus and to control the time-domain pulse waveform changing apparatus.
