摘要
光纤布拉格光栅(FBG)具有抗电磁干扰、耐腐蚀、体积小和成本低等优点,而飞秒激光制备的FBG更具有耐高温的独特优势。文章首先对飞秒激光刻写FBG的3种主流方法,包括飞秒激光相位掩模板法、飞秒激光直写法和飞秒激光全息干涉法进行了介绍,对比分析了各种制备方法的优缺点,其次着重对飞秒激光制备的FBG的温度、压力(应变)和折射率传感的原理及其应用进行了综述,最后指出了飞秒激光制备的FBG在河水、湖泊和海洋等领域环境监测中的应用前景。
Fiber Bragg Grating(FBG)has the advantages of anti-electromagnetic interference,corrosion resistance,small size and low cost.Moreover,the FBG fabricated by femtosecond laser has the unique advantages of high temperature resistance.Firstly,three mainstream methods for writing FBG with femtosecond laser are introduced,including femtosecond laser phase mask method,femtosecond laser direct writing method,and femtosecond laser holographic interferometry.The advantages and disadvantages are compared and analyzed.Secondly,the principle and application on temperature,pressure(strain)and refractive index sensing of FBG prepared by femtosecond laser are reviewed.Finally,the future development of FBG fabricated by femtosecond laser in lakes,oceans and other fields is prospected.
