Basics of laser processing technology, laser processing application examples, and their key points

Understanding Laser Processing Technology

Laser processing technology has become an integral part of various industries due to its precision, efficiency, and versatility.
It involves using a laser beam to cut, engrave, weld, or alter materials in a way that traditional methods cannot achieve.
The technology is based on the principles of light amplification through stimulated emission of radiation, which allows for a concentrated and controlled application of energy.

The effectiveness of laser processing lies in its ability to focus a high-intensity beam on a small area, thereby allowing it to process a diverse range of materials, such as metals, plastics, glass, and ceramics.
The technology offers significant advantages over conventional techniques, including minimal material waste, reduced processing time, and higher precision.

How Laser Processing Works

Laser processing begins with the generation of a laser beam, which is amplified to the desired power level.
This beam is directed through a series of mirrors and lenses to focus it onto a specific area of the target material.
By adjusting the focus and movement of the laser, operators can manipulate the material in various ways.

Several types of lasers are used in processing, with the most common being CO2 lasers, fiber lasers, and Nd:YAG lasers.
Each type of laser has its own set of characteristics, making it suitable for different applications.
CO2 lasers are typically used for cutting and engraving non-metallic materials, while fiber lasers are preferred for metal processing due to their higher power efficiency and precision.
