Abstract
Superradiant waveguide evanescent‐type dye lasers are realized by polyurethane top layers containing Rhodamine 6G and Rhodamine B respectively on single‐mode glass waveguides with N2 uv laser pumping. A new determination method of gain factor (negative absorption coefficient) by active guide length dependence of a triangle shape top layer is proposed.This publication has 12 references indexed in Scilit:
