CO₂ Fractional Laser Machine: RF Tubes or Ordinary Glass Tubes?

When purchasing a CO₂ fractional laser machine, many buyers notice that the market price varies significantly from one model to another. The main reason lies in the core configuration — whether the machine uses RF tubes or ordinary glass laser tubes.
This article provides a detailed comparison between the two and explains how their configurations impact performance and cost.

1. Comparison Overview

1) Power Output
Glass Tube: Laser power is unstable.
RF Tube: Stable energy output ensures consistent treatment results.
2) Lifespan
Glass Tube: Service life is about 1–2 years.
RF Tube: Service life ≥ 3 years.
3) Energy Performance
Glass Tube: Laser energy decreases significantly from beginning to end.
RF Tube: Energy remains stable throughout the entire treatment process.
4) Beam Spot & Density
Glass Tube: Spot size and density are uneven.
RF Tube: Smaller, denser, and more uniform beam spots.

2. Core Advantages of RF Tubes

Equipped with a 30W high-power metal RF laser tube imported from USA Access, CO₂ fractional laser machines with RF tubes provide the following benefits:
No need for water refilling or cooling, making operation easier.
Lower maintenance costs and longer service life.
Korea-imported seven-joint articulated arm ensures precise and stable beam delivery.
Stable, uniform, and safe energy output.
Laser Power: 1–30W
Working Mode: Continuous Mode

3. Practical Application Comparison

RF Laser Tubes: Best suited for fractional skin resurfacing, wrinkle removal, scar revision, vaginal tightening, and pigment removal—applications that require high precision and energy stability.
Glass Laser Tubes: Typically used in basic cutting machines, low-cost beauty instruments, or entry-level systems.

For example, the Cocoon CO₂ Fractional Laser Machine adopts a 30W RF laser tube imported from USA Access, ensuring more stable energy output and longer service life.
It uses a 10600 nm wavelength, offering four working modes and a Korea-imported seven-joint articulated arm.
With its high water absorption rate, this wavelength enables the laser to cut, vaporize, and coagulate tissue precisely, delivering accurate and efficient treatments.

4. Conclusion and Recommendations

RF CO₂ Laser Tube: Ideal for professional medical and aesthetic institutions that pursue high stability, precision, and long-term ROI. Delivers stable energy, smaller focal spots, and extended lifespan — making it the premium choice for high-end fractional laser systems.
Glass CO₂ Laser Tube: Suitable for entry-level users or educational applications. Lower initial cost but requires frequent maintenance, has a shorter lifespan, and experiences faster energy decay.
