Hamamatsu Photonics (Hamamatsu, Japan - President and CEO: Akira Hiruma) has developed a compact tabletop size power laser system that emits high-power light pulses of 1 joule at a high repetition rate of 300 hertz by using laser diodes as pumping light sources that provide an output power boosted 3 times compared to ordinary pumping laser diodes. Increasing the output power of laser systems usually has an adverse effect on equipment size and repetition rate. This new power laser system solves that problem and delivers high output power and a high repetition rate despite its compact size.

This new power laser system improves production efficiency in laser machining processes such as laser cleaning for removing small debris and contaminants and will also find uses in new applications such as laser forming for fabricating metal materials by laser pulse shock and laser peening for extending lifetime of metal parts.

This new power laser system was developed by the team of Toshiyuki Kawashima, Deputy Director of the Industrial Development Center, Hamamatsu Photonics Central Research Laboratory. Part of this laser system’s development relied on a R&D program called “Ubiquitous Power Laser for Achieving a Safe, Secure and Longevity Society” managed by Yuji Sano program manager under the ImPACT Program (Impulsing Paradigm Change through Disruptive Technologies) sponsored by the Japanese Cabinet Office Council for Science, Technology and Innovation. We intend to push ahead to develop this power laser system toward its successful commercialization. This newly developed power laser system will be on display at the Hamamatsu Photonics exhibition “PHOTON FAIR 2018” to be held at Act City Hamamatsu (Naka-ku, Hamamatsu City, Japan) for 3 days starting from November 1 (Thursday).
