1000W 915nm ファイバー結合ダイオードレーザー

Brandnew は、高密度空間ビーム結合 (DSBC) のアイデアを導入し、kW レベルのポンプ源を用いて実験的に証明しました。現在、シングルエミッタの出力は電気光学効率で15W~30W@BPP≈5-12mm・mradに達しています。<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.
