Overview
- FO is a fiber laser oscillator with high quality and high power.
- Product variations from output power 1 kW to 8 kW.
- FO has the following four unique features that do not allow other fiber lasers to compete.
(1) Single amp oscillator architecture resistant to back reflected light
(2) Wide range of power control: 1% to 100%
(3) Output power stability of ± 1% or less
(4) Various beam mode (single mode, multimode, and ring mode) - Not only supplying oscillating unit alone, but also we support to you for integrating laser processing system.
Application
- Welding of various kind of metal materials
- Processing of highly reflective material
- Surface treatment of metals, concrete, etc.
- Microfabrication
- Cutting of metal, ceramic, etc.
Single amp oscillator architecture resistant to back reflected light
Avoiding unexpected troubles caused by back reflected light.
- Unique structure with anti-reflectiveness makes it possible to welding process of materials with high reflectance such as copper and aluminum.
- Irradiation from vertical angle is available by FO, while conventional laser require irradiation from tilted angle in order to avoid troubles brought by back reflected light.
- You may safely use galvano scanner connected to FO, though it often bring reflected light back to oscillating unit.
Structure of conventional fiber laser
Laser generated by oscillator is amplified before irradiation. In case that reflected light enter into oscillator, its power exceeds a capacity of oscillator, then it occurs troubles such as damage.
Structure of single amp oscillator
Oscillator alone generate high power laser without using amplifier. There is less trouble because power of back reflected light always lower than oscillator’s capacity.
Example of Processing "Butt welding : copper"
Power control range
A wide range of processing conditions may be adoptable. You may try various kind of processing with single unit of FO.
- Power control lower than 10% is available
(output power control range: 1 to 100%).
Power stability
Real-time power monitoring system achieves fine output control.
- Power control adjustment by real-time power monitoring is done every 30 μsec.
- Power stability: <± 1% realized.
*(Reference) Specification value of conventional fiber laser is ± 2 ~ 3%
Long time continuous running power test (65 hours)
- Average output power : 2,080 W
- Power deviation: 1.4 W
- Power deviation / Average Output: 0.06%
*Measured by 2 kW laser unit
Various beam mode
- Single mode
- Multi mode
- Ring mode
