Demonstration of a 150-kW-peak-power, 2-GHz-linewidth, 1.9-μm fiber gas Raman source.
TL;DR: If a tunable pump laser is used, a high-peak-power, narrow-linewidth, broadly tunable, 2-μm fiber laser source can be easily achieved, and operation close to atmospheric pressure makes it more convenient in future applications.

Optical Constants of Water in the 200-nm to 200-microm Wavelength Region.
George M. Hale,Marvin R. Querry +1 more
TL;DR: Extinction coefficients k(lambda) for water at 25 degrees C were determined through a broad spectral region by manually smoothing a point by point graph of k( lambda) vs wavelength lambda that was plotted for data obtained from a review of the scientific literature on the optical constants of water.
