The paper presents a reliable organic solid-state tunable laser. Distributed-feedback lasing of [3-(2-benzothiazolyl)-7-(diethylamino)coumarin] (Coumarin 6) in a polymeric waveguide was achieved using holographic dynamic gratings. A low-threshold energy of lasing from Coumarin 6 was achieved in a poly(N-vinylcarbazole) (PVCz) matrix waveguide and in a tris(8-quinolinolato)aluminum (Alq) dispersed polystyrene (PS) matrix waveguide. For both PVCz / Coumarin 6 and PS/Alq/ Coumarin 6, the effective energy transfer played a significant role for lowering a lasing threshold. By rotating a Lloyd mirror, simply tunable lasing from 516 to 546 nm was achieved.
