Dilas
DILAS, the diode laser company’s, new fibre-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 fibre-coupled module produces >300 W output power at 976 nm from a 200 µm/0.22NA fibre in a total package weight of ~300 g. 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 optimises the beam quality from the diode laser bar enabling high-efficiency fibre coupling.
Breaking this critical weight-to-power ratio is a major milestone for a high-brightness fibre-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.
