Hamamatsu Photonics has developed new laser diode (LD) modules that are extremely compact yet emit a uniform high-intensity beam of light. These new LD modules consist of stacks of LD bars that are designed and manufactured in-house and 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 by 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. From here onward, Hamamatsu will be developing these LD module products even further to meet more wide-ranging market needs. These newly developed LD modules were on display at NEDO’s booth at the Optics & Photonics International Exhibition OPIE ’18 held in Pacifico Yokohama.
