Continuous laser amplification in a monomode fiber longitudinally pumped by evanescent field coupling.
Amplification of continuous laser radiation propagating in a monomode optical fiber was obtained by evanescent field coupling within a pumped dye solution deposited in the neighborhood of the fiber core. A factor-of-25 signal gain was recorded for 632.8-nm He-Ne radiation and DCM dye solution.
