New Light Weight, Fiber-Coupled Tailored Bar (T-Bar) Module Meets Critical Metrics for Defense Market



February 5, 2013

Mainz, Germany, February 5, 2013 – DILAS, the diode laser company’s, new fiber-coupled tailored bar module meets the critical metric of <1 kg/kW of overall module weight to optical output power, while maintaining nearly 50% efficiency. In terms of specifications, this fiber-coupled module produces >300W output power at 976nm from a 200µm/0.22NA fiber in a total package weight of ~300g. The device is also of suitable brightness to meet the requirements for flyable systems on lightweight aircraft and UAVs.

DILAS’ key innovation is the combination of the high-power, high-brightness, tailored diode laser bar and the lightweight, compact, low thermal impedance heat sink. In addition, micro-optics attachment is completely automated which optimizes the beam quality from the diode laser bar enabling high-efficiency fiber coupling.

Breaking this critical weight-to-power ratio is a major milestone for a high-brightness fiber-coupled diode laser product. Aside from the defense applications cited, many potential applications in other markets are opened such as industrial and medical where the overall size, weight reduction, and efficiency can reduce system ownership and operating costs.

DILAS, the diode laser company, is focused on delivering the most innovative technologies and advanced product solutions in the industry. Founded in 1994 in Mainz, Germany, with operations in North America and Asia, DILAS designs, develops and manufactures quality high-power, high-brightness semiconductor laser components, modules and systems, including fiber-coupled products for worldwide distribution.
