  • LASER DEVICE
    Publication number: 20140064307
    Abstract: A laser device includes a partially reflective mirror for separating laser light into monitor light and output light, a light output monitor device for detecting the intensity of the monitor light from the partially reflective mirror, a controller for controlling the intensity of the output light from the partially reflective mirror by controlling the output of a laser light source on the basis of a detection value of the light output monitor device, and a power meter device for detecting the intensity of the output light from the partially reflective mirror during a predetermined calibration time period, wherein the controller calibrates the output of the light output monitor device on the basis of a detection value of the power meter device.
