The Shanghai Puri 60W-100W CO2 laser tubes excel in engraving and cutting applications, providing exceptional spot mode, power, and longevity for most domestic laser machinery manufacturing needs.

Laser Tube Working Principle: Harness high-pressure discharge to stimulate CO2 molecules, generating powerful laser emissions.

Laser Tube Laser Wavelength: Operating at a precise 10.6 μm, ensuring optimal performance in various applications.

Laser Tube Laser Mode: Engineered for low order mode, delivering consistent and efficient laser output.

Laser Tube Water-Cooling: Utilizes purified water, maintaining an ideal temperature range of 10-35°C for peak performance.

Laser Tube Working Environment: Optimal conditions include a temperature range of 5-35°C, humidity levels of 10-60%, and a clean, pollution-free environment.

Laser Tube Working Current: Maintain a suitable current of 16~22mA, as excessive current impacts both power output and tube lifespan.

Laser Tube Safety Demand: Exercise caution with CO2 tubes, which emit invisible light and high pressure; protective eyewear is highly recommended.

Laser Tube Laser State: Monitor for attenuation-pink indicates normal function, while white suggests reduced power; replace when performance declines.

Laser Tube Laser State:
1. During installation, support the laser tube at two points, positioned at 1/4 of its length on each side, for stability.
2. Ensure proper cooling water flow from above-in to below-out; minor adjustments can impact spot and power.

To date, Puri laser tubes have reached over 60 countries, marking a significant global presence and trusted performance.
