Abstract

The embodiment of the invention provides an optical element laser preprocessing system and belongs to the field of optical material laser preprocessing.The optical element laser preprocessing system comprises a light source device, an analyzer and a reflection device.A sample to be processed is arranged in an optical propagation path between the analyzer and the reflection device.Preprocessed laser beams output by the light source device are emitted into the analyzer, the preprocessed laser beams passing the analyzer are emitted to a preset processing point of the sample to be processed, the preprocessed laser beams passing the sample to be processed are reflected by the reflection device and then emitted to the preset processing point of the sample to be processed, and the preprocessed laser beams passing the sample to be processed are emitted by the analyzer.The optical element laser preprocessing system effectively improves laser preprocessing efficiency of optical elements, and reduces cost of optical element laser preprocessing.

Description

technical field [0001] The invention relates to the field of laser pretreatment of optical materials, in particular to a laser pretreatment system for optical elements. Background technique [0002] In order to improve the laser damage performance of optical components, usually before the components are placed on the shelf, laser pretreatment is performed on the light-passing area of ​​the component with laser energy below the damage threshold, that is, the optical component is irradiated with a laser beam. Through laser pretreatment, the component damage threshold can be increased by a maximum of 1 to 2 times. Such a substantial improvement in damage performance is of great significance for the application of optical components. At present, laser pretreatment has become the first choice for high-power laser system optical components before they are put on the shelves. Necessary steps. [0003] During the pretreatment process, the irradiation flux of the laser pulse needs t...
