Problems solved by technology

The disadvantage of this method is that it is necessary to constantly adjust the position of the sample surface so that it is in the focal plane of the converging laser, otherwise it will not be possible to complete the processing of the ceramic material due to insufficient energy of the irradiated laser.

Abstract

The invention discloses a device and method for pattern processing on the surface of a ceramic ball by using femtosecond laser, and belongs to the technical field of laser processing of ceramic surfaces with irregular shapes. The device comprises programming software, a femtosecond laser amplifier, a half wave plate, a polarizer, a converging lens, a scanning galvanometer, the ceramic ball with the irregular shape and a loading table with a three-dimensional precision displacement platform. The half wave plate, the polarizer, the converging lens and the scanning galvanometer are placed at theoutput end of the femtosecond laser amplifier in sequence. The ceramic ball with the irregular shape is placed on the loading table with the three-dimensional precision displacement platform. Deflection of the scanning galvanometer is controlled by using the programming software, and controlling over the trajectory and speed of femtosecond laser filamentation movement is achieved, so that femtosecond laser processing of three-dimensional parametric patterns on the surface of the ceramic ball is completed, and the device and method for pattern processing on the surface of the ceramic ball by using the femtosecond laser can show the extremely important function in the fields of precision processing of functional ceramic objects and carving of art ceramic products.

Description

technical field [0001] The invention belongs to the technical field of laser processing of ceramic surfaces with irregular shapes, and in particular relates to a device and method for pattern processing on the surface of ceramic balls using a femtosecond laser. Background technique [0002] Ceramic materials are a kind of inorganic non-metallic materials made of natural or synthetic compounds through forming and high-temperature sintering. It has stable physical and chemical properties such as corrosion resistance, wear resistance, and high temperature resistance. The new ceramic materials discovered in recent years have unique advantages in performance, such as insulation, piezoelectricity, non-magnetism, small thermal expansion coefficient, etc., so they are widely used in metallurgy, machinery, chemical industry, electronics, aerospace and in medical and other industries. With the increasing demand for ceramic products in different fields, people's requirements for high-...
