Modelling of Laser Output from a Pulsed Laser to Achieve a Consistent Cutting Process

摘要

Laser processing device and method that stores characterization information representing specifics of a specific laser used for processing a material and forms a model to control the laser based on the laser performance specifics. This control sets a spacing between leading edges of sequential pulses of optical energy output by the laser, that when output by the laser, creates a laser power output with a consistent amount of pulse overlap between the sequential pulses, e.g., 50% overlap. This control is specific to the specific laser and creates a very consistent processing using the laser, e.g., a cut.

主权项

1. An apparatus for processing a material using a laser, comprising:
a memory, storing characterization information representing specifics of a specific laser used for processing a material; a computer, running a program that uses said characterization information to set a laser control command, including a spacing between leading edges of sequential pulses of energy output by the laser, that when output by the laser, creates a laser power output with a consistent amount of pulse overlap between said sequential pulses; and outputting said command to control the laser to process the material in a way that changes the material by a consistent amount while maintaining a consistent amount of average power applied to said material and maintaining a consistent amount of overlap between said sequential pulses.
