In industrial settings, consistency is king. One second of delay or variation can throw off an entire production line. That’s where CO₂ laser tubes shine—literally. These glass tubes are the beating heart of laser systems that cut, etch, and mark materials across countless industries. But what exactly do they do? And how do you choose the best one?
Since 2009, PURI Laser has crafted CO₂ laser tubes that balance power, precision, and lifespan. Here’s a breakdown of how they work, what they can do, and what to watch for when choosing yours.
Think of it as a sealed, gas-filled flashlight for infrared light. Inside, a high-voltage current excites a mix of carbon dioxide, nitrogen, and helium. That mix ignites and emits a laser beam at 10.6 μm. Mirrors at the ends bounce it into a focused, powerful beam used to cut or engrave materials.
Unlike fiber or diode lasers, CO₂ tubes excel at working with non-metals: acrylic, leather, wood, rubber, paper—you name it.
You’ve probably seen their work in:
Cutting: acrylic, MDF, PVC foam boards, textiles
Engraving: logos, serial codes, decorative designs on wood, glass, leather
Trimming/perforation: flexible packaging, filters, automotive interiors
Clients from laser machine builders to distributors in Europe, Southeast Asia, the Middle East, and Africa rely on CO₂ tubes for steady, reliable operation.
The process is surprisingly elegant:
High-voltage electricity excites the gas inside the sealed glass tube.
The mixture generates a population inversion.
Mirrors at each end create an optical cavity.
One mirror lets part of the infrared laser escape.
That beam is channeled through lenses to deliver pinpoint power to a target.
Depending on wattage and quality, a CO₂ tube might effortlessly slice through 25 mm of acrylic—or engrave lines as fine as 0.1 mm.
The tube can make or break your laser setup. Here are five must-check features:
Feature | What to Know |
Power Output (W) | 60W–180W+ options. Higher power = deeper, faster cuts (e.g., 130W ≈ 10–15 mm acrylic). |
Beam Quality | TEM₀₀ or near-Gaussian beams deliver cleaner, sharper cuts—PURI Laser targets this. |
Lifespan & Stability | Quality tubes last 8,000–10,000 hours with minimal power drop. PURI uses catalyst coatings to boost longevity. |
Cooling Needs | Tubes > 100W need dedicated chillers and stable water flow to prevent overheating. |
Traceability & Certification | Serial numbers, QC records, power tests—essential for reliability and warranty claims. |
CO₂ tubes can look the same on the shelf, but subtleties matter:
Gas mix must be precise
Seals need to hold tight
Electrode alignment and coating are critical
At PURI Laser, every step—from gas calibration to leak testing—is automated, tracked, and verified. Our tubes ship with serial numbers, QC tags, and tested output. That way, our OEM and distributor partners avoid reruns, failures, and messy support calls.
The laser tube isn’t a minor part—it’s the core of your system’s performance. Get it wrong, and you risk lower speeds, poorer cuts, or system downtime. Choose well and you unlock stable operation, precision results, and a long working life.
So if you're looking for CO₂ tubes that are laser-tested, traceable, and performance-ready, PURI Laser has been supplying partners worldwide since 2009 with tubes that work as hard as they do.
