High power tunable wavelength visible laser system using gain-managed nonlinear fiber amplifier as a seed pulse

We have demonstrated through simulation a few Watts, tunable wavelength, visible laser system. We used gain-managed nonlinear fiber amplifier output as the broadband seed pulse as opposed to the standard white light generation. The advantages of gain-managed nonlinear seed pulse compared to conventional methods are uniform and high spectral energy density. Furthermore, the inherent quasi-linear chirp of the proposed seed pulse is the key factor in tuning the output wavelength from 500nm to 600nm arbitrarily. Our tunable laser has potential use in high-demand applications such as spectroscopy, imaging as well as free electron laser facilities.
