Láser de diodo acoplado de fibra de 1000 W y 915 nm

Brandnew introdujo la idea de la combinación de haz espacial denso (DSBC) y la demostró experimentalmente con una fuente de bomba de nivel de kW. Actualmente, la potencia de salida de los emisores individuales ha alcanzado 15W~30W@BPP≈5-12mm·mrad con eficiencia electroóptica.<60%. This makes it possible for the high-power pump source with optical fiber output to maintain high brightness, small volume, and light weight. With commercial available chips, Brandnew achieved 1000W output at 915nm (or 976nm) from a 200μm core diameter 0.22NA fiber is obtained and mass of ≈400g. In the future, with increasing diode chip brightness and electro-optical efficiency, the pump source with high power and mass ratio will have an important role in small size and high power fiber lasers, which will become an active driver for defence and industrial applications.
