For the feasibility of metal ion reduction induced by the femtosecond laser two-photon absorption of organic polymer material,the experiments were taken in silver nitrate and polyvinylpyrrolidone film mixture at the ratio of the amount of substance of 1:1.In the developed two-photon fabrication system,a single line with the width of 25μm and a 4mm ×0.4mm plate were fabricated.The X-ray photoelectron spectrum revealed that the main element in the product was silver,and the range of resistivity from 10-3Ω·m to 10-5Ω·m was calculated by measuring the resistance.The result shows that using two-photon induced reduction of metal ions,the reaction region can be controlled well,and it is helpful for the conductive metallic microstructure fabrication.
