本文首次报道用脉冲红外激光诱发等离子体瞬时反应制备超精细氧化铁粉末,并对其形成机制做了初步探讨。 实验采用TEA—CO_2激光为光源,脉宽为150ns,输出波长为10.6μm,激光光束经锗透镜聚焦在金属Zn靶上,真空配气系统真空 This paper reports for the first time the use of pulsed infrared laser induced plasma instantaneous reaction of ultrafine iron oxide powder, and its formation mechanism to do a preliminary discussion. The TEA-CO_2 laser was used as the light source. The pulse width was 150ns and the output wavelength was 10.6μm. The laser beam was focused by the germanium lens on the metal Zn target.
