1000 Vt 915 nm tolali diodli lazer

Brandnew zich fazoviy nur kombinatsiyasi (DSBC) g'oyasini taqdim etdi va uni kVt darajadagi nasos manbai bilan eksperimental ravishda isbotladi. Hozirgi vaqtda yagona emitentlarning chiqish quvvati elektro-optik samaradorlik bilan 15W ~ 30W@BPP≈5-12mm·mrad ga yetdi.<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.
