Hamamatsu Photonics has developed compact laser diode modules that emit a uniform high-intensity beam capable of pumping high-power industrial pulsed solid-state lasers. The company says these new laser diode modules will improve production efficiency during laser machining and processing.
The new LD modules consist of stacks of LD bars that the company designed and manufactures in-house, and that they say offer the world’s highest level output power. These new LD modules now make it possible to pump 10-joule class and 100-joule-class high-power industrial solid-state lasers and so will help improve production efficiency during laser processing, such as in laser peening for hardening the surface of metallic materials used for transport and shipping equipment.
These new LD modules were developed in part with assistance from the “Development of advanced laser processing with intelligence based on high-brightness and high-efficiency next-generation laser technologies” project supported by NEDO (New Energy and Industrial Technology Development Organization), a national research and development agency in Japan. Hamamatsu Photonics will also be developing these LD module products further to meet more wide-ranging market needs. These newly developed LD modules will be on display at NEDO’s booth (G-26) at the Optics & Photonics International Exhibition OPIE ’18 to be held in Pacifico Yokohama (Nishi-ku, Yokohama, Japan) for three days from the 25–27 April 2018.
