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 N/sub 2/ 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.
