Understanding Laser Processing

Introduction

Laser processing refers to the use of focused laser beams to alter, shape, or treat materials with extreme precision and control. It has become an essential technology in industries such as electronics, automotive, aerospace, medical devices, and energy, offering advantages such as non-contact processing, high-speed operation, and the ability to work with complex geometries.

How Laser Processing Works

Laser beams deliver concentrated energy to a material’s surface, which can melt, vaporize, or modify its structure. Depending on the application, the process can be continuous or pulsed, and can include heat-based or photochemical effects. Various parameters—like wavelength, power, and pulse duration—can be adjusted to achieve the desired results on different materials.

Key Benefits

• High Precision: Enables micro-processing and intricate detailing.
• Non-Contact Operation: Reduces mechanical wear and risk of contamination.
• Versatile Applications: Applicable to metals, polymers, ceramics, and composites.
