Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and more specifically, to a laser cutting device for a column. Background Art

[0002] Laser cutting is achieved by applying high-power density energy generated by laser focusing. Under the control of a computer, the laser is discharged through pulses, thereby outputting controlled repetitive high-frequency pulse lasers, forming a beam of a certain frequency and pulse width. The pulse laser beam is conducted and reflected through the optical path and focused on the surface of the object being processed through a focusing lens group, forming fine, high-energy density light spots. The focal spot is located near the surface to be processed, and the material to be processed is melted or vaporized at an instant high temperature.
