How long does a CO2 laser tube last?
All glass CO2 laser tubes degrade over time with lifespans ranging from as little as 3 months to 3 years. Basically, the CO2 inside the tube breaks down into Carbon Monoxide and Oxygen with use. If you overdrive the tube, it just accelerates this process and reduces the working life.
