Near-infrared and midinfrared radiation has been generated by means of multiple-order stimulated Raman scattering in hollow-core silica fibers filled with CBrCl3 and CCl4 and pumped by Nd:YAG laser radiation. Radiation between 1.2 and 2.3 µm has been generated in 300-cm-long, 12-µm core-diameter liquid-filled fibers using peak powers of 11 kW. Single-mode liquid-core waveguides were constructed by using CCl4-CBrCl3 mixtures of adjustable refractive index.
