用ＣＯ２激光辐照诱导醋酸铜乙醇溶液反应，在石英衬底上激光直写得到金属铜线，研究了不同的写线速度对激光直写的效果，得到一个最佳的写线速度，该写线速度随激光强度的增大而提高。 CO2 laser irradiation was used to induce the reaction of copper acetate in ethanol solution. Laser direct writing on quartz substrate was used to obtain metal copper wire. The effect of different write line speed on laser direct writing was studied and an optimal write line speed was obtained. Linear velocity increases with increasing laser intensity.
