1000W 915nm 파이버 결합 다이오드 레이저

Brandnew는 DSBC(Dense Spatial Beam Combination) 아이디어를 도입하고 kW급 펌프 소스를 사용해 이를 실험적으로 입증했습니다. 현재 단일 이미터의 출력 전력은 전기 광학 효율로 15W~30W@BPP≒5-12mm·mrad에 도달했습니다.<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.
