micromechanical technology, and micro-optical technology. It uses the high energy density and good directionality of the laser beam to process within the micron range after focusing to achieve precision processing of tiny parts. Because laser micro manufacturing technology has the advantages of non-contact, powerlessness, no heat-affected zone, high precision, and high efficiency, it has been widely used in fields such as microelectronics, micromechanics, and microoptics.

Relevant theories or principles of laser micromachining

The basic principle of laser micromachining is to use the high energy density and good directionality of the laser beam to process within the micron range through focusing. After the laser beam is focused, the energy density is extremely high, which can instantly heat the material to the evaporation temperature, generate high-pressure steam, push the material to rapidly expand, and form tiny holes. This is the basic process of laser micromachining.

In the laser micromachining process, the energy density and focusing accuracy of the laser beam are two important parameters. Energy density determines the processing depth and processing speed of laser micromachining, and focusing accuracy determines the processing accuracy and processing quality of laser micromachining. Therefore, to achieve high-precision and high-efficiency laser micromachining, the energy density and focusing accuracy of the laser beam must be precisely controlled.
