Problems solved by technology

Mirror reflective surface treatment adopts the method of coating high reflective film on the metal panel, the reflectivity of the laser can reach more than 97%, which can meet the protection requirements of the laser measuring device, but the reflected light needs to be protected, especially when the reflected light is along the When the incident light direction returns to the original path, it will cause serious damage to the laser components, which limits its application; the diffuse reflection surface is treated by sandblasting or polishing the surface of the metal panel to form a diffuse reflection surface, and the reflection of the laser is about 80%. , the reflected light is diffusely reflected in multiple directions, which avoids the damage to the components on the optical path and reduces the protection requirements, but it has the problems of low surface reflectivity and weak resistance to laser radiation damage. Usually, only For lower power laser protection

Embodiment Construction

[0024] After extensive and in-depth research on improving the laser damage resistance threshold of the material surface in the high-energy laser parameter measurement technology, a surface treatment process for improving the laser damage resistance threshold of the metal material was proposed, and a specific processing method was realized through a large number of experiments.

[0025] Such as figure 1 As shown, the surface of the metal substrate 1 is sandblasted to form a diffuse reflection surface, and then sequentially processed with a zinc film, a nickel film and a gold film. The material of the metal panel is aluminum or copper. The specific processing steps are as follows:

[0026] (1) Perform high-temperature heat treatment on the selected metal panel to remove the residual stress inside the material and avoid deformation of the material during processing and laser irradiation;

[0027] (2) Clean and sandblast the metal panel after heat treatment. In order to achieve a...

Abstract

The invention discloses a laser-irradiation-resistant diffuse reflection metal panel and a manufacturing method thereof. After a metal base plate is subjected to sand blasting so as to become a diffuse surface, a zinc film, a nickel film and a golden film are sequentially coated on the diffuse surface, the laser-resistant damage threshold of the metal panel can be improved effectively, and at the same time, the damage of a component on the optical path caused by mirror reflectors is avoided.

Description

technical field [0001] The invention relates to a metal panel resistant to laser radiation and a processing method thereof, in particular to a metal panel resistant to laser radiation with diffuse reflection characteristics and a processing method thereof. Background technique [0002] In the measurement of high-energy laser parameters, due to the high energy of the incident laser, the energy is converted into heat and deposited on the laser receiving surface of the measuring device, which in turn causes damage to the measuring device. Therefore, effective protection of the measuring device is required in practical applications to ensure the measurement The safety and stability of the equipment itself. There are mainly two types of protective panels currently used: specular reflection surface treatment and diffuse reflection surface treatment. Mirror reflective surface treatment adopts the method of coating high reflective film on the metal panel, the reflectivity of the la...
