Basics and applications of laser processing technology, the latest processing technology and its key points

Understanding Laser Processing Technology

Laser processing technology is a highly advanced method used in various industries to cut, engrave, and mold materials.
This technology utilizes a concentrated beam of light, or laser, to manipulate materials with high precision and accuracy.
It’s increasingly popular due to its versatility, efficiency, and ability to perform complex operations with minimal waste.

The Basics of Laser Processing

Laser processing fundamentally involves directing a laser beam onto a material to alter its properties.
The beam’s intensity, duration, and the medium through which it’s delivered can be tailored to achieve the desired effect.
There are different types of lasers used for processing, including CO2 lasers, fiber lasers, and Nd:YAG lasers, each suited to various materials and tasks.

CO2 lasers are versatile and often used for cutting, welding, and engraving non-metallic materials.
Fiber lasers are excellent for high-precision tasks, especially on metals, due to their smaller spot size and high output power.
Nd:YAG lasers are known for their effectiveness in drilling and scribing applications.
