Low intensity noise high-power tunable fiber-based laser around 1007 nm

We report the development of a tunable, low-noise, all-fiber, single-frequency, linearly polarized high-power master oscillator power amplifier operating over 20 nm, from 1017 nm down to 997 nm. Using Ytterbium highly-doped silica fiber with large mode area, more than 3 W of 997 nm signal was obtain...

Description
Summary:We report the development of a tunable, low-noise, all-fiber, single-frequency, linearly polarized high-power master oscillator power amplifier operating over 20 nm, from 1017 nm down to 997 nm. Using Ytterbium highly-doped silica fiber with large mode area, more than 3 W of 997 nm signal was obtained with less than 2 % of ASE. These figures keep improving with operating wavelength, to reach more than 16 W and 0.03 % of ASE at 1017 nm. The optical signal to noise ratio exceeds 40dB for the worst case up to more than 60dB. In addition, relative intensity noise remains very low over the whole tuning range (-130dBc@10kHz) down to-160dBc at 10 MHz. This robust laser has a strong potential to be a new workhorse for demanding applications in this spectral range.
