7-2-5 Laser oscillator
A CO 2 (carbon dioxide) laser oscillator is installed in the head. The laser beam output from the oscillator is scanned and
focused to mark or process the target materials.
„
Effect from deterioration
Laser output characteristics such as laser power will deteriorate over time due to aging of oscillator. As the laser output
characteristics deteriorate, symptoms such as ununiform marking density, chipped characters, or unstable processing
quality, etc. may occur.
Also, as cooling efficiency of the oscillator decreases because of the usage environment, the electronic parts in the
oscillator 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, incomplete
processing) 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 exceeded
12,000 hours.*
• Alarm for laser error occurred.
* The replacement interval may differ depending on the usage environment and marking conditions.
ンㄆㄇㄆㄓㄆㄏ㄄ㄆ
• The laser pumping time exceeds 12,000 hours, the “!” symbol is displayed on the maintenance screen of the Laser
Marker NAVI smart and MAINTENANCE OUT (Y13) of I/O terminal block turns ON.

How to confirm operating hours
Go to the “Maintenance” screen and select “Operating data”.
“Laser pumping time [h]” is displayed.
