Hamamatsu Photonics successfully developed an industrial pulsed laser system that produces a pulse energy of 250 J (joules) which is the world’s highest energy among LD-pumped lasers. The development of this laser system stems from the “Research and Development of Next Generation Laser Processing Technology” project supported by the NEDO, which is a national research and development agency in Japan. This new laser system boosts the energy storage capability of the laser medium as well as beam quality to deliver more than double the energy amplification capability while still maintaining the same size as currently available industrial pulsed lasers.

Acquiring and integrating the processing-machining data from this laser system will allow a useful database to be built for optimizing laser processing conditions by using artificial intelligence (AI). This will not only streamline laser processing-machining tasks but also open up new frontiers in energy and medical and applications.

Hamamatsu Photonics plans to announce this achievement at the NEDO booth during the OPIE ’21 (OPTICS & PHOTONICS International Exhibition 2021). This is Japan’s largest optoelectronics exhibition and will be held at the Pacifico Yokohama (Nishi-ku, Yokohama, Japan) from Wednesday June 30th through to Friday July 2nd 2021. Laser-machining samples will also be on exhibit.
