[14p-PA12-7] Highly efficient fs laser multi-photon reduction by TiO2 nanoparticles in solution

〇Kan Umetsu1, Hiroaki Nishiyama2 (1.Yamagata Univ., 2.Grad. Yamagata Univ.)

Keywords:femtosecond laser,multi-photon reduction

We show highly efficient fs laser reduction by TiO2 nanoparticles dispersed in solution. Multi-photon reduction was markedly enhanced by adding TiO2 nanoparticles to the solution. Metallic structures were stably formed at laser translation speed 15 times higher than that of the solution without nanoparticles.
