High-Power, Independently Wavelength, Power, and Linewidth Tunable Ytterbium Fiber Laser

We report a high-power, independently tunable wavelength, linewidth, and power, continuous-wave Ytterbium-doped fiber laser. Our system is based on a simple master oscillator power amplifier configuration, which decouples the output power from the output wavelength and linewidth. We demonstrate a continuously tunable laser system that can generate any output power level up to and beyond 100 W, wavelength from 1050 to 1100 nm, and linewidth tuning of 2.5 times from 0.4 to 1 nm completely independent of each other.
