The laser energy stabilizing device comprises a silicon / copper circular polarizer, a light path channel and a light absorption plate, and the silicon / copper circular polarizer is arranged in the light path channel; a laser beam emitted by a laser generator enters the light path channel and enters the silicon / copper circular polarizer at 45 degrees, and part of the laser beam is reflected by the silicon / copper circular polarizer, is emitted at 45 degrees and is absorbed by the light absorption plate, and the other part of the laser beam is converted into a circular polarized light beam through the silicon / copper circular polarizer, the circular polarized light beam is irradiated on light splitting units, and the circular polarized light beam is reflected by at least one light splitting unit and finally reaches a laser cutting station. According to the laser energy stabilizing device, the equipment with the laser energy stabilizing devise, and the application of the laser energy stabilizing device of the invention, the stability of laser path energy is realized, laser spots are uniform, energy output is stable, the equipment maintenance frequency is reduced, and the equipment utilization rate is improved; and the laser energy stabilizing device is especially suitable for the field of laser cutting of polaroids and OCA optical cement.

Description

technical field [0001] The invention relates to the field of laser energy control, in particular to a laser energy stabilization device and its equipment and application. The invention is mainly applied to laser cutting polarizers and OCA optical adhesives. Background technique [0002] Due to its good directivity, the laser beam is often widely used as a straight line reference in processing equipment. However, due to the influence of environmental conditions and other factors, the further improvement of laser direction stability is restricted, which limits the use of laser in ultra-precision processing equipment. further applications in. [0003] Existing CO 2 When the laser beam of the laser generator is emitted, it is easily affected by the environment, resulting in unstable laser energy output, different laser spot sizes, frequent product cutting in laser cutting equipment, and large fluctuations in the size of the fusion edge, which affect production capacity. There...
