We offer a CO2 laser refill service and repair of optical and electronic failures. Our service includes functional testing, parameter logging and helium leak checking, residual gas analysis, resonator adjustment and modulation testing. Finally, we carry out a 30-minute stability test.
Recharging CO2 lasers is a complex process that requires extensive technical knowledge and the necessary infrastructure. Most quality European or US-made laser engraving machines incorporate laser tubes with RF technology. These types of laser tubes are very efficient and productive. They can last for many years and are highly stable. Recharging this type of laser is very cost-effective considering the number of hours of work it can perform.
Brands of laser tubes that we refill
The CO2 laser brands we refill include ULS / Ulsinc / Universal laser tube, Synrad, Coherent, Iradion, and similar tubes rebranded by Epilog or Trotec.
We can also recharge and/or repair Chinese-made RF laser tubes, but in many cases the recovery cost can be higher than the purchase price of a new tube.
Refilling Synrad lasers or any other brand of sealed metal tube is our specialty, including Iradion tubes with ceramic core, both air-cooled and water-cooled.
Technology for proper recharging
We have a state-of-the-art turbomolecular vacuum pump that provides adequate decontamination for proper restoration of optimal laser performance. This part of the process is critical and fundamental to ensuring laser quality and stability very close to the original state.
Gas ion lasers with excess or negative pressure, low-power CO2 lasers, or lasers with defective optics don’t necessarily need a costly new tube. Since 2004, we have been one of the few providers worldwide to operate state-of-the-art turbomolecular vacuum pumping stations for servicing CO2 lasers, argon-krypton and mixed gas systems.
By using high-purity noble gases and a mass spectrometer for residual gas analysis, we are able to restore ion lasers to optimal gas pressure and thus significantly extend their service life.
Service Guarantee
Once the laser refill is successfully completed, you will receive a quality report detailing the parameters obtained during the stability test and other data.
Our service is backed by a 12-month warranty that covers any malfunctions related to repairs performed. Damage to external optical components or damage caused during transport is not covered.
In most cases, the laser tube can be successfully restored, but if the damage or defects prevent the tube from being repaired, we do not charge.
Send us your CO2 laser tube from anywhere worldwide — we handle the recharging at our specialized workshop.

Frequently Asked Questions
-
What does laser tube refurbishing involve?
Laser tube refurbishing extends the working life of CO2 tubes that have lost power or stability due to gas degradation or contamination. Using state-of-the-art turbomolecular vacuum pumps, we decontaminate and refill the tube with high-purity gases to recover its original performance. This process is far more cost-effective than purchasing a brand-new tube, especially for premium RF lasers. Refurbished tubes are tested for stability before being shipped back to the customer. -
How can you tell when a laser tube is running out of power?
When you notice a loss of cutting power after a period of operation, it’s a common symptom of internal gas degradation. -
How long does a laser tube last?
It depends on the use and working conditions; between 3 and 5 years is the most common lifespan. -
Should you replace the laser tube or refill it?
Most of the time, it’s more cost-effective to reuse the CO2 laser cartridge. RF laser tube recharge is our area of specialization, particularly for sealed metal-tube models from Synrad and similar manufacturers. These tubes are highly efficient and durable, making a recharge extremely cost-effective relative to the hours of operation they provide. -
Do you have replacement parts available?
We can supply new and refurbished tubes for some brands and models. Contact us for more information. -
Laser engraver machine not cutting
If your laser engraver’s tube is no longer cutting through materials it used to, the most likely cause is internal gas degradation reducing output power. This gradual loss of cutting power is one of the clearest signs that a CO2 laser tube needs recharging rather than replacing. Before assuming the tube is beyond repair, it’s worth having it tested, since most tubes in this condition can be successfully restored. Refilling is typically far cheaper than buying a new tube. -
Do you offer on-site service?
No, you will need to disassemble the laser tube, package it properly, and ship it to our warehouse. We can provide support if you have any questions about the disassembly process; in most cases, it’s quite straightforward. -
I am located outside Europe. What is the shipping and service process?
Please contact us so we can review your case and assess the problem. You’ll need to send the tube via a door-to-door shipping service; DHL, UPS, or FedEx are the most well-known. Contact your local office for quotes. -
Do you offer pickup and delivery service?
Yes. For customers based in EU member states, we can coordinate pickup and return shipping of your laser tube via our authorized logistics partner. Applicable charges will be itemized on your invoice. Please contact us for further details. -
What payment methods do you accept?
Once the laser tube is repaired, you will need to make a bank transfer. -
How long does it take to repair a laser tube?
It depends on the tube model and the problems we find; it can take more or less time. The average repair time is 21 days. -
What happens if it can’t be repaired?
It’s not common, but there’s a possibility that the damage to the tube will prevent its recovery. In that case, we don’t charge anything, but we don’t cover shipping costs or customs fees, which you will have to pay. This represents a shared risk that both parties acknowledge.
