4-2-6 Laser oscillator
A fiber laser oscillator is installed in the controller. The laser beam output from the oscillator is delivered through the fiber
cable to the head. The laser is scanned and focused in the head and emitted to 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 laser power density or unstable marking 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 laser 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 the laser marking or processing.
• The laser power measured with a commercial power meter has decreased by 20%, compared to the delivery status.
• The total radiation time has exceeded 30,000 hours.*
• Alarm for laser error occurred.
* The replacement interval may differ depending on the usage environment and conditions.
