DILAS, Mainz, Germany, has increased its range of high-brightness, fiber-coupled diode laser modules based on tailored bar (T-Bar) architecture. With this new addition, the fiber-coupled modules are now capable of delivering up to 200 W output power from a 200 micron (NA 0.22) fiber at 976nm.

The tailored bar architecture is specifically designed to achieve high-brightness output while maximizing fiber coupling efficiency for an overall high-efficiency product. The T-Bar was developed so that an automated active optics alignment can be utilized for efficient fiber coupling into a 200µm fiber. This device is a monolithic multi-emitter source which takes advantage of handling multiple emitters during each individual manufacturing step to lower complexity and enhance reproducibility of the beam quality and hence the fiber coupling.

These T-Bar fiber-coupled modules are ideal for research and development usage in direct diode applications as well as for fiber and solid-state laser pumping.
