FO series ARM (Adjustable Ring Mode), which is a fiber laser we handle, has the beam for center and ring. Both beams are separated coaxially and reach the processed area. This beam mode is completely a new processing mode that could not be realized by conventional laser welding and cutting.

In addition to this laser oscillator, we could achieve sputter reduction during welding, dramatic improvement for the bead surface and improvement of welding strength by combining robots and optical heads under the optimum conditions for the target materials.

We will support you to verify processing performance and to find optimum conditions by ARM at our demonstration facility.

Adjustable Ring Mode（Patented）

The beam irradiated from ARM is separated coaxially for center and ring, and reaches the processed area. Each beam of center and ring is generated inside the oscillator without using optical system and is transmitted to the exit window while maintaining beam quality.

Center + Ring

This completely new beam mode enables advanced processing in welding, cutting and surface treatment, which have never been possible by conventional lasers. Reducing sputters during welding for galvanized steels, dramatic improvement of welding quality for aluminum materials, and other new processing technologies are expected to be developed. Various combinations with this independently controllable laser bring you significant changes for your laser processing.

Both center and ring beams can be controllable independently

Resistant to reflected beam by single amplifier
(Possible to irradiate with 90 degree toward the material)

Output laser power range 1-100% Output laser power stability +/- 1%

Reduction of sputter and porosity

Optimizing process conditions each for variety kind of materials
Thanks to ring shape beam, there is no limitation on processing directionality
Achieves efficient welding for highly reflective materials such as aluminum and copper by irradiating laser at 90 degree
Reducing sputters during welding process

Only center beam

Only ring beam

Both center and ring beam

Resistance of back reflected beam

It is possible to avoid unexpected troubles caused by back reflected beam.

Unique structure against back reflected beam enables to weld the materials with high reflection such as aluminum and copper.
FO-series is available to irradiate with vertical angle such as 90 degree, while conventional lasers require irradiation from tilted angle in order to avoid troubles brought by back reflected beam.
You may safely use Galvano scanner connected to FO-series, though it often bring reflected beam back to laser oscillator.

Conventional
fiber laser

Laser generated by oscillator is amplified before irradiation. Because the reflected beam is also amplified and returned to the oscillator, problems such as damage are likely to occur.

Oscillator generates high power laser without using amplifier.
It significantly reduces the risk of damage due to the return of reflected beam.

Power control

A wide range of process conditions are applicable.
You may try various kinds of process with FO-series.
Power control lower than 10% is available.
(output power control range: 1 to 100%)

Power stability

●Average output power: 2,080W ・Output standard deviation: 1.4W　●Standard deviation / average output power: 0.06%
*FO-series with maximum output power 2kW was used for this measurement.

Laser welding: Aluminum

Laser welding process for aluminum materials used to bring defects such as porosities and undercuts. In addition, a lot of sputters generated during the process, damaged product itself and process equipment. We can solve these problems utilizing ARM laser.
