Laser Marking Machine with RF Excited CO2 Laser Tubes

What is a RF CO2 Laser?

A RF (Radio frequency) CO2 laser is a laser generator that uses an RF power supply to excite carbon dioxide gas to produce laser light. Its working principle is based on stimulated emission, where the RF power supply excites the gas to achieve population inversion. When population inversion occurs, the recombination of electrons and holes releases photons. These photons are reflected within the resonant cavity to form coherent laser light. The RF electric field controls the laser gain, gradually increasing the light intensity, and ultimately outputs a high-quality laser beam through the resonant cavity.

The RF laser requires maintaining a vacuum environment within the chamber and uses a cooling system to control the operating temperature, preventing performance degradation due to temperature rise, which could affect the normal operation of the equipment.

Key components include the resonant cavity, RF power supply, and cooling system. The RF laser uses a fully enclosed metal tube as the resonant cavity, which offers better thermal stability, strength, and dust resistance compared to ordinary materials, enabling it to withstand higher power output. The fully sealed design prevents performance instability caused by gas consumption, effectively enhancing lifespan and reliability.

Advantages of RF CO2 Lasers

• Higher Electro-Optical Conversion Efficiency: Enables efficient energy utilization with a discharge efficiency of over 25%.
• Stable Continuous Output Power: More suitable for large-area marking and processing.
• High-Frequency Laser Generation: High-frequency discharge produces lasers with higher repeatability and stability, making it ideal for precision processing.
• Small Laser Spot Diameter: Superior beam quality, making it more suitable for high-precision fine engraving and marking.
• Compact Design: The RF laser is small in size and has a compact structure, allowing integration into various machinery and small devices, saving space.
• Higher Reliability and Stability: Offers longer service life and can be used in various working environments.
• Faster Marking and Engraving Speed: Higher precision with a smaller heat-affected area, achieving speeds of up to 15,000 mm/s.
• Constant Temperature Cooling System: Eliminates the need for frequent gas replacement, resulting in lower operating costs.

Details of RF CO2 laser marking machine

CRD RF CO2 laser source

Compared to DC glass tube lasers, RF laser sources can operate at high repetition rates. Additionally, they offer superior beam quality—the RF beam is smaller and more uniformly dense than the DC-excited beam, and they maintain consistent characteristics and density across the entire power scale.

Galvanometer scanner

Capable of 24-hour continuous operation with excellent stability, high positioning accuracy, faster marking speed, and strong anti-interference capabilities.

F=160mm field lens

Features strong focusing performance, multi-layer coating, and a long service life.

Multi-hole worktable

Made of aluminum alloy for enhanced durability. The multi-hole design facilitates quick positioning and can be used in combination with side backing plates, offering adjustable positions for versatile configurations.

Push-pull keyboard drawer

The push-pull keyboard drawer allows you to store the keyboard when not in use, saving space and effectively preventing dust from entering.

Hand crank

Using this device in conjunction with a scale allows for precise adjustment of the distance between the laser head and the workpiece.

Control panel

The control panel is located below the display screen and is equipped with separate control buttons for each functional component for easy operation.
