摘要
硫系玻璃作为一种特殊的红外光学玻璃,在中红外波段光子器件领域应用中展现出巨大的优势。激光诱导周期性表面结构,其周期接近或小于入射激光波长,在红外微纳光学器件领域具有广阔的应用前景。首先,分别采用单点及激光直写两种加工方式系统地研究了飞秒激光在As_(2)S_(3)玻璃上诱导周期性结构随脉冲数量的演化过程。其次,对低脉冲数量及高脉冲数量下所形成的两种不同的周期性结构(低空间频率周期性结构及高空间频率周期性结构)的形成机制进行了系统地分析。最后,通过采用飞秒激光直写技术在As_(2)S_(3)玻璃表面制备出了大面积的周期性结构,并对该周期性结构的光学颜色特性进行了测试和探究。
As a special infrared optical glass, chalcogenide glass shows great advantages in the application of photonic devices in the mid-infrared band. Laser-induced periodic surface structures, whose periods are close to or less than the incident laser wavelength, have broad application prospects in fabricating micro-optical infrared devices that exceed the diffraction limit. This study investigates the evolution process of the periodic structure induced by femtosecond laser on As_(2)S_(3) glass with a pulse number using two processing methods, single point and laser direct writing. First, the formation mechanism of two different periodic structures(low and high spatial frequencies) formed under low and high pulse numbers was analyzed. Then, a large-area periodic structure was fabricated on the surface of As_(2)S_(3) glass using femtosecond laser direct writing technology, and the optical color properties of the periodic structure were tested and explored.
