Professional Recharge Service for Universal Laser Systems UL-25 CO₂ Laser Tubes

If your Universal Laser Systems UL-25 25W CO₂ laser has lost power, become unstable, or can no longer reach its original output, the laser tube may not necessarily need to be replaced.

For some older Universal UL-25 RF CO₂ laser tubes, professional laser tube refurbishment and gas recharge can be a practical alternative to purchasing a complete replacement.

What Is the Universal UL-25?

The Universal UL-25 is a 25W RF-excited CO₂ laser source used in Universal Laser Systems equipment for engraving and material processing.

The ULS-25 system specification lists a 25 Watt CO₂ laser source, while ULS RF CO₂ laser technology uses an RF-excited design rather than a conventional high-voltage glass CO₂ tube.

This RF technology provides fast laser response and stable beam performance, making it suitable for precision engraving applications.

Why Does an UL-25 Laser Lose Power?

After years of operation, an RF CO₂ laser can gradually lose output power.

Common symptoms include:

Reduced engraving depth
Slower cutting or engraving
Weak or inconsistent laser output
Laser power dropping after warming up
Machine requiring higher power settings for the same result
Laser failing to reach its rated output
Unstable laser operation

In some cases, the problem may be related to the condition of the laser tube and its gas mixture.

However, low laser power can also be caused by other components such as optics, RF power supply, cooling, or control electronics. A proper diagnosis should therefore be performed before deciding on a recharge.

Can a Universal UL-25 Be Recharged?

Depending on the condition of the laser tube, a professional refurbishment process may restore its performance.

A typical refurbishment process may include:

Initial laser output testing
Inspection of the laser tube and resonator
Vacuum processing
Gas-system processing
Gas recharge
Sealing and leak testing
RF operation testing
Laser output testing
Final performance verification

The actual process depends on the condition and construction of the individual laser tube.

Recharge or Replace the Laser?

For an older Universal laser system, customers often have two options:

Option 1 — Replace the Laser Tube

A replacement tube is the simplest solution when the original tube is beyond economical repair.

However, replacement RF laser sources can be expensive, particularly for older Universal Laser Systems equipment.

Option 2 — Professional Laser Tube Recharge

If the original UL-25 tube is structurally sound and suitable for refurbishment, professional recharge may extend its usable service life.

This can be an attractive option for customers who want to keep their existing Universal laser system running without immediately investing in a new laser source.

Why Choose Professional RF Laser Recharge?

A professional recharge is more than simply adding gas to the tube.

The laser must be properly processed and tested to achieve stable operation.

A qualified service provider should pay attention to:

Vacuum quality
Gas composition
Internal tube condition
RF excitation
Cooling condition
Optical alignment
Output power
Power stability
Leak integrity

Incorrect processing can result in unstable laser output or shortened service life.

Universal UL-25 Recharge Service

We provide RF CO₂ laser tube refurbishment and recharge services for customers using Universal laser systems.

Our service is suitable for customers who have an older Universal UL-25 25W laser tube and are experiencing reduced laser power or performance problems.

Before accepting a tube for refurbishment, we recommend providing:

Laser tube photos
Model number
Serial number
Current laser power, if available
Machine model
Description of the problem
Photos of the laser tube and connectors

Our technicians can then evaluate whether the tube is a suitable candidate for refurbishment.
