Title:
LASER OUTPUT OPTICAL CABLE
Document Type and Number:
WIPO Patent Application WO/2022/105749
Kind Code:
A1
Abstract:
The embodiments of the present application provides a laser output optical cable, mainly comprising: an energy transmission optical fiber and a laser cutting head connector for connecting a laser output head and a laser cutting head, the energy transmission optical fiber and the laser cutting head connector being sequentially connected on an optical path; the laser output head comprises an end cap; the laser cutting head connector is provided with at least one spatial diaphragm; clear apertures of the spatial diaphragms are determined on the basis of the distance between a virtual light emitting point and the spatial diaphragms and a divergence angle of the laser output beam after passing through the end cap; and the virtual light-emitting point is determined on the basis of the end cap. According to the laser output optical cable provided in the embodiments of the present application, the space diaphragms are added in the laser cutting head connector located between a cutting head collimation unit and the laser output head, so as to filter out part of the light beams larger than the clear apertures, especially the trailing part of the light spots, so that the incidental heat effect on a nozzle is greatly reduced, the cutting effect is effectively improved, and safe operation of laser equipment is ensured.
