Broadband infrared generation in liquid-bromine-core optical fibers
Abstract
A new Raman-gain medium suitable for use throughout the infrared spectral region is described. Hollow silica fibers with liquid-bromine cores are shown to have very large Raman-gain coefficients (gamma = 1.7 x 10 to the -8th cm/W at 1.1 micron with a Raman shift of 312/cm). The liquid-bromine core, being a homonuclear diatomic material, has no first-order infrared absorption, and transparency between 1 and 16 microns has been verified. Broadband infrared radiation between 1.1 and 4 microns was generated by stimulated Raman scattering in bromine-core fibers pumped with 1.06- and 2.11-micron radiation.
