LASER LIGHT IRRADIATION SYSTEM, LASER LIGHT IRRADIATION METHOD, AND RECORDING MEDIUM

WIPO Patent Application WO/2013/094758

A1

In order to handle output variations in a laser light oscillator in which the output of laser light varies by a fixed amplitude around a setting value for a very short period rather than being fixed, the present invention adjusts the output of the laser light oscillator so that the actual output value for laser light matches a setting value, thus making possible a suitable cutting process for an optical film. This laser light irradiation system is provided with: a laser light oscillator that oscillates laser light; a beam splitter splits the laser light oscillated by the laser light oscillator into first laser light and second laser light and irradiates a film with the first laser light; a measurement device that measures the intensity of the second laser light split by the beam splitter; and a correction device that calculates an output value for the laser light oscillator from the second laser light intensity measured by the measurement device and makes the output value for the laser light oscillator approach the setting value.
