Ultra-Bright Diode Laser Emitters for Pumping High-Power Fiber Amplifiers
nLight proposes a novel semiconductor laser device operating at ~976 nm with a spatially single mode laser that is separately addressable to generate a few hundred milliwatts of power and then subsequently amplified to>10 watts with a separate electrical contact in a larger gain area while preserving the beam quality resulting in>1000 MW/cm2-Sr. We expect electrical-to-optical power conversion efficiency of>55% by using Super High Efficiency Diode Sources (SHEDS) design. We will also develop a concept for packaging these devices in nLight"s Gen-2 Pearl module.
