CSR

The Advanced Technology Laboratory integrates research groups engaging in the three technological fields of photonics, energy and electronics, and conducts research in a comprehensive manner in these fields, including overlapping areas. A characteristic feature of the laboratory is that members conducting R&D for materials and those focusing on the aforementioned research fields collaborate together to make achievements under the slogan, "Material to Products." Their research results are used in the development of automotive products, fiber lasers, high-frequency functional devices, and telecommunication components. We will continue conducting activities to develop next-generation technologies and deliver attractive products that will be needed by customers around the world.

The laboratory has contributed to the advancement of the field, including providing optical fibers for use in experiments on large-capacity transmission, which are conducted to develop next-generation optical communication systems. We will continue using our optical technologies to take on the challenge of developing next-generation communication devices.

The laboratory will continue to take on the challenge of developing materials for eco-friendly technologies, including yttrium-based high-temperature superconductive wires that enable efficient energy transmission as well as dye-sensitized solar cells that are optimal for use in the energy harvesting (eco-friendly power generation) field.

The laboratory will focus on leading-edge technologies, including those for sensor systems, circuit boards, and printed electronics that helps deliver high value-added products based on printing technologies.

Pulse fiber lasers found widespread applications in the micromachining field, especially in metal marking and scribing and now require higher performance.
Fujikura has developed a high-power pulse fiber laser rated at 75 W (FLP-G75S). This laser has achieved the industry's top-level features including high-power (75W average output power, 1.1mJ pulse energy) and high beam quality (M2?1.7). They will contribute greatly to productivity increases by enabling machining in hard-to-machine areas (Fig.1), deeper and higher speed machining (Fig.2). In addition, the new device has been substantially more compact and lighter in weight than existing ones, which helps drastic improvements in flexibility in assembling to laser equipment or systems.
