利用飞秒激光诱导水击穿的方法在双面单模光纤中制作了法布里-珀罗涉仪(FPI)腔。然后用弧光放电对FPI腔进行退火热处理，使腔内表面光滑。整个制作过程具有操作简单、效率高的特点。制作的FPI腔具有理想的干涉仪光谱，反射损耗仅为-3分贝，条纹能见度接近30分贝。它具有高灵敏度(1147.48 nm/RIU)、良好的线性(99.93%)、良好的重复性、高的实际测量精度(1.29x10(-4RIU))、大的测量范围和良好的温度不敏感特性，是一种非常可靠的液体折射率传感器。(C)2014年美国光学学会
The Fabry-Perot interferometer (FPI) cavity in a single-mode fiber with two open faces was fabricated by using the method of femtosecond laser-induced water breakdown. Then the FPI cavity was annealed by the arc discharge to greatly smooth its internal surface. The whole fabrication process features simple operation and high efficiency. The fabricated FPI cavity exhibits a perfect interferometer spectrum with reflection loss of only -3 dB and fringe visibility of almost 30 dB. It can be used as a perfectly reliable liquid refractive index sensor, as it exhibits high sensitivity (1147.48 nm/RIU), good linearity (99.93%), good repeatability, high actual measurement accuracy (1.29 x 10(-4) RIU), large measurement range, and good temperature insensitive characteristic.
