Laser diode modules for pumping industrial lasers

Hamamatsu Photonics has developed new laser diode modules that are extremely compact yet capable of emitting a uniform high-intensity beam of light. The new modules consist of stacks of laser diode bars that offer an exceptionally high level of output power and therefore make it possible to pump 10-joule class and 100-joule-class high-power industrial solid-state lasers. 

The modules will help improve production efficiency during processes such as laser peening for hardening the surface of metallic materials used for transport and shipping equipment. 

These new laser diode 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.
