Introduction

CO2 laser marking machines are extensively used in industrial applications for their ability to mark, engrave, or cut various materials with high precision. These machines employ a gas laser that utilizes carbon dioxide as the lasing medium to produce an intense beam of infrared light.

Working Principle of CO2 Laser Marking Machines

CO2 lasers function by exciting a gas mixture (typically 10-20% carbon dioxide, 10-20% nitrogen, 1-5% hydrogen, and the remainder being helium) within a sealed tube. When an electrical current passes through this gas mixture, the energy causes the CO2 molecules to vibrate and produce photons.

The generated photons are then amplified by mirrors at both ends of the laser tube; one of the mirrors is partially transparent, allowing some light to exit as a laser beam. The wavelength of the CO2 laser is approximately 10.6 micrometers, which is ideal for non-metallic materials like glass, wood, ceramics, and certain plastics.

Technical Specifications

Key parameters of a CO2 laser marking machine include:

• Power Output: Ranges from 10W to 200W, influencing the depth and speed of marking.
• Beam Quality (M²): Typically around 1.1, indicating the beam's focusability and quality.
• Pulsed vs. Continuous Wave: Pulsed lasers offer controlled energy bursts, while continuous waves are steady.
• Engraving Speed: Up to 7000 millimeters per second, depending on the material and laser power.
• Resolution: Up to 1000 DPI (dots per inch), affecting the detail and clarity of the mark.
