Abstract

AbstractThe frequency dependence of the gain factor of stimulated Raman scattering was measured using tunable dye lasers as signal and pump light sources. In CCl4 and C2Cl4 peak gain factors of 1.3 × 10−9 cm/W and 1.7 × 10−9cm/W were obtained for the major Raman lines with a frequency shift of ν0 = 458 cm−1 and 447 cm−1, respectively. From the experimental gain factor a threshold power of 0.2 W was estimated for a liquid‐core fiber filled with C2Cl4 (diameter 10 μm and length 1 km).
