Furukawa Electric's Industrial Lasers

Made-in-Japan fiber laser incorporating Furukawa Electric technologies

High-power fiber lasers incorporating the communication technologies of Furukawa Electric, the first company in the world to practically apply optical fiber cable.
All of the core components are made by the Furukawa Electric Group, made in Japan fiber lasers with the superior level of quality.
Moreover, the fusion of Furukawa Electric’s technologies with our partner companies contribute to the realize world-class laser processing quality.

Furukawa Electric has a history of fiber lasers to meet the customer's needs of the times.

Furukawa Electric has incorporated a variety of new technologies (optical fiber, semiconductor lasers, optical fusion technology, etc.) cultivated through optical communications into its fiber lasers, and has been a Japanese pioneer in the field of fiber laser development.

Beginning with visible light lasers and low-power fiber lasers, in 2011 we producted the first 300 W/500 W single-mode fiber laser in Japan.

In 2008, we established an "Application Lab", we work with customers to solve their issue.

We have worked on new products such as 10 kW+ class high-power fiber lasers, and a Blue-IR hybrid laser suitable for the laser for pure copper.

In 2019, we established a Customer Support Center to providing comprehensive support for a variety of customer and field issues.

We will continue to offer solutions tailored to the needs of our customers.

Feature 1 World's highest beam quality

Our single-mode fiber lasers have the world's smallest core diameter (14 µm) and the highest beam quality.

Moreover, our multi-mode fiber lasers by leveraging own beam coupling technology are able to maintain the highest quality.

This high beam quality ensures the same level of processing performance with lower laser power than other lasers.

Beam profile M2=1.06 (single-mode)

Feature 2 High reflected light resistance

When processing highly reflective material such as copper, high reflected light returns into the fiber, and this can lead to laser breakdown.

Furukawa Electric has verified no damage occurs even at vertical incidence using its proprietary measures for dealing with reflected light.

Feature 3 Flexible beam forming by beam mode control technology

(Note) The optical head with beam mode control function was jointly developed with Furukawa Denshi Co., Ltd.

The key feature of our beam mode control technology is characterized by flexible beam design.

Spattering suppressed with beam mode control

Spattering can also be reduced using beam mode control technology, even under conditions in which spattering would normally occur.

In order to offer our customers the best possible processing quality, we also verify the effect of the improvements in processing quality obtained using beam mode control technology in our Application Lab.

  • Without beam mode control

    Significant spattering

  • With beam mode control

    Minimal spattering

Features 4 Core technology on the bases of laser technology and material background

We evaluate quality and develop laser processing technologies in collaboration with our metal material background and development department by leveraging our strengths in handling a wide range of metal products. By combining laser technology with material background, we are able to offer our customers the best laser processing solutions to meet their needs.

1 kW single-mode processing example Processing performance equivalent to 2 kW multi-mode laser

With its high beam quality and light focusing property, Furukawa Electric's 1 kW single-mode laser offers processing performance equivalent to that obtained with a 2 kW multi-mode laser. Processing of up to 5 mm thick stainless steel, 3 mm thick aluminum, and 1 mm thick copper is possible.



This laser is capable of delivering the same tensile strength as the theoretical value for the welding of difficult-to-process materials aluminum and copper.


Multi-mode processing example Deep penetration by high beam quality fiber laser

This is a high-power multi-mode fiber laser combining a single-mode fiber laser boasting high beam quality with low-loss beam combiner technology. This laser is capable of achieving the deep penetration by high beam quality fiber laser, making it suitable for remote welding also.
