摘要
A dye laser based on the soluble conjugated polymer,Poly[1,8-octanedioxy-2,6-dimethoxy-1,4-phenylene-1,2-ethenylene-1,4-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 wavelength region with the peak at 450 nm.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.
