1507-2-5 Laser oscillatorA CO2 (carbon dioxide) laser oscillator is installed in the head. The laser beam output from the oscillator is scanned andfocused to mark or process the target materials. Effect from deteriorationLaser output characteristics such as laser power will deteriorate over time due to aging of oscillator. As the laser outputcharacteristics deteriorate, symptoms such as ununiform marking density, chipped characters, or unstable processingquality, etc. may occur.Also, as cooling efficiency of the oscillator decreases because of the usage environment, the electronic parts in theoscillator may become defective and unable to irradiate the laser. Replacement interval• Deterioration in quality of marking and processing (streaking and density reduction of the marking, incompleteprocessing) is observed.• Setting a large value for the laser power is not reflected in the quality of marking and processing.• The laser power measured with a commercial power meter has decreased by 20%, compared to the delivery status.• Three to five years have passed since the date of delivery, or the total operating time of laser pumping has exceeded10,000 hours.*• Alarm for laser error occurred.* The replacement interval may differ depending on the usage environment and marking conditions. How to confirm operating hoursDisplay the “Runtime data” panel of the “Maintenance”screen of Laser Marker NAVI smart, and check the laserpumping time.
