Does every CO2 laser tube undergo a 100% full-power aging test before packaging, and how long is the total burn-in time?

Yes, absolutely. Every single CO2 laser tube manufactured in our facility undergoes a mandatory 100% full-power aging test prior to final packaging.

As an quality-driven origin factory, we enforce a comprehensive ~10-hour multi-stage burn-in protocol to completely eliminate infant mortality and guarantee steady-state optical output:

• Stage 1: High-Voltage Outgassing & Resonant Cavity Activation (~2 Hours): Initial gas discharge burn-in to neutralize trace internal impurities and stabilize electrode emission.

• Stage 2: Continuous Full-Power Core Aging (~6 Hours): Operating continuously at 100% rated current to verify long-term thermal equilibrium, power drift tolerance (<∓3%), and TEM00 spatial beam profile integrity under full load.

• Stage 3: Pre-Shipment Cold-Start Verification (~2 Hours): A final operational test conducted post-cooling to confirm instant ignition reliability, power stability, and zero vacuum degradation.

• Serialized Quality Tracking: Real-time laser power, operating voltage, and beam spot profiles recorded during the aging process are logged under the tube’s unique barcode and attached as a factory inspection certificate.
