Laser oscillator
The following type of the laser oscillator is installed in the laser marker. The laser beam output from the oscillator is
scanned and focused to mark or process the target materials.
• LP-400 series: A CO
2
(carbon dioxide) laser oscillator is installed in the head.
• LP-V/LP-W series: A fiber laser oscillator is installed in the controller and the laser beam is delivered to the head through
the fiber cable.

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.
⿎ Replacement interval
• Deterioration in quality of marking or processing (density reduction, incomplete marking or processing) is observed.
• Setting a large value for the laser power is not reflected in the quality of marking or processing.
•
The laser power measured with a commercial power meter has decreased by 20%, compared to the delivery status.
• LP-400 series: Three to five years have passed since the date of delivery, or the total operating time of laser pumping
has exceeded 12,000 hours.*
• LP-V/LP-W series: The total radiation time of laser has exceeded 30,000 hours.*
• Alarm for laser error occurred.
* The replacement interval may differ depending on the usage environment and marking conditions.
⿎ How to confirm operating hours
Display the “System information” on the “Environment setting” screen and check the total laser pumping time and radiation
time.
