摘要
A novel two photon photoninitiated polymerization is reported. The results of the study show that the two photon polymerization of TMPTMA can be initiated by means of 4,4 bis(di n butylamino) E stiebene(BDBAS) under 600 nm strong laser. The light source that we used for the two photon polymerization is a YAG pumped dye laser whose oscillating wavelength repetition rate and single pulse energy are 600 nm, 10 ns and 15 mJ, respectively. The peak power density of radiation light tight focused by means of bojective lens is 3.8 GW/cm 2. The relative mechanism of the polymerization is discussed. [WT5HZ]
