Embodiment Construction

[0031] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Homogenization sheets are commonly used for the homogenization of existing lasers. However, the manufacture of traditional homogenization sheets requires complex processes such as lithography, corrosion, and cleaning. Production and manufacturing require investment in lithography, cleaning, and other equipment, which makes the input cost high. Photoresist and chemical etching, especially the waste water and waste gas produced by the corrosion process, pollute the environment, and can only etch glass, and cannot process the cheap methyl methacrylate corrosion-resistant materials. Based on the above problems, the present invention provides a processing method and a processing device for a high-power semiconductor laser light homogenization sheet. The device and method adopt a physical processing technology, the prod...

Abstract

The invention provides a processing method and a processing device of a semiconductor laser light homogenizing sheet, and solves the problems of high manufacturing cost, complex manufacturing process,large environmental pollution, large light loss and the like of the existing laser light homogenizing sheet. The processing method comprises the following steps: S1, a base plate is placed on a workbench of a three-dimensional moving device, and at least one sharp needle is arranged above the base plate; and S2, the workbench or the sharp needle is moved, the distance between the base plate and the sharp needle in the Z direction is controlled, and the sharp needle is enabled to draw lines or press points on the surface of the base plate, so that lines or grooves are formed on the surface ofthe base plate to complete the manufacturing of the light homogenizing sheet. The processing device comprises a three-dimensional moving device and at least one sharp needle, a workbench of the three-dimensional moving device is used for placing the base plate, and the sharp needle is arranged above the base plate.

Description

technical field [0001] The invention belongs to the field of semiconductor lasers, and in particular relates to a processing method and a processing device for a light homogenizing sheet of a semiconductor laser. Background technique [0002] Due to its high brightness and good divergence angle, lasers have important applications in many aspects such as laser display and laser lighting. However, since the laser power generally has a Gaussian distribution, in most cases, in order to increase the brightness, multiple lasers need to be coupled and output, so the obtained light field is not uniform. At present, homogenization sheets are generally used for homogenization of laser light, but the manufacture of traditional homogenization sheets has the following problems: [0003] First, the process flow is complicated, and a photolithography machine needs to be used to make a photolithography plate, and the process flow of photolithography etching is relatively complicated; [0...
