Introduction

CO2 laser systems are integral to various industries due to their efficiency and precision. Understanding the working of a CO2 laser galvo head is crucial for optimizing operations and ensuring effective application in material processing.

Working Principle of CO2 Laser

CO2 lasers operate by exciting carbon dioxide gas to produce laser beams in the mid-infrared range, typically around 10.6 micrometers in wavelength. The energy provided excites the CO2 molecules, and as they transition back to a lower energy state, they emit photons, forming a laser beam.

Galvo Head Mechanism

The galvo head in a CO2 laser system is responsible for directing the laser beam precisely over the material surface. This section discusses the role and functionality of galvo mirrors controlled by galvanometer scanners, which enable rapid and accurate positioning of the laser spot.

Galvanometer scanners utilize electromagnetic fields to rotate mirrors to predefined angles. The movement speed and precision are critical, with typical rotation speeds reaching up to 20,000 RPM, ensuring high precision in industrial applications.

Specific Parameters and Numerical Analysis

Key parameters influencing the performance of CO2 laser galvo heads include:

• Beam Diameter: Typically varies from 5 mm to 20 mm, impacting the focus and cut precision.
• Pulse Width: Affects the thermal impact on materials. Pulse widths range from microseconds to nanoseconds.
• Scan Speed: Maximum speeds up to 10 m/s are achievable, affecting processing efficiency.
• Resolution: Galvanometer mirrors provide resolutions up to 16,384 DPI, allowing intricate designs.
