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 we designed and manufacture 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, we will be developing these LD module products even 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 3 days from April 25 (Wed) to 27 (Fri).

 

※Pumping:

Process in which atoms and molecules are excited to a higher energy level by absorbing light. Solid-state pulsed lasers emit laser light with energy amplified by irradiating low-power seed light onto the laser medium that is pumped or excited with LD modules.
