LASER RECORDING METHOD AND LASER RECORDING DEVICE

Title:

LASER RECORDING METHOD AND LASER RECORDING DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/013017

Kind Code:

A1

Abstract:

A laser recording method is for processing a recording object with laser light emitted from a laser light source. The laser recording method includes: detecting a moving speed of the recording object with a location of the laser light source when the laser light source emits laser light, as an observation point, while moving at least one of the recording object and the laser light source; and correcting power output of the laser light set such that an amount of energy applied by the laser light per unit area of the recording object is constant even if the moving speed is changed, to compensate energy loss derived from thermal diffusion occurring on the recording object based on the moving speed detected at the detecting.
