DILAS, Mainz, Germany, has introduced a state-of-the art tailored mini-bar architecture for high brightness fiber coupling, which is capable of delivering 135 W output from a 200-micron (NA 0.22) fiber at 976 nm.
The tailored mini-bar architecture by DILAS is specifically designed to realize high brightness output while maximizing fiber-coupling efficiency for an overall high efficiency product. The tailored mini-bar was developed so that the optical parameter of the emission fit into the 200-micron fiber with the most simple and inexpensive optics. This device is a monothical-multi single emitter source that takes advantage of handling multiple emitters during each individual manufacturing step to lower complexity and overall costs.
With scalable concepts further modules will soon be available, such as 976 nm, 200 W, 200 µm and 976 nm, 500 W, 200 µm.
These fiber-coupled, multi-bar modules are ideal for direct diode applications as well as for fiber and solid-state laser pumping.
