Abstract A dye laser based on the soluble conjugated polymer, Poly[1,8-octanedioxy-2,6-dimethoxy-1,4-phenylene-1,2-Ethenylene-l, 4-phenylene-1,2-ethenylene-3,5-dimethoxy-1,4-phenylene], has been fabricated. The laser was pumped by light pulses from the third harmonic radiation of an Nd:YAG laser. The lasing was observed in the blue wave- length region with the peak at 450nm. The threshold energy is about 19μJ. The energy conversion yield of the laser is about 3.4%. The maximum peak power of the laser output pulse arrives at about 20kW.
