Abstract
We report on the creation of Fiber Bragg Gratings (FBGs) based sensors in large mode area (LMA) fibers. By using a quintupled Nd:YVO4 laser at 213 nm wavelength, FBGs are produced in conventional double clad fibers with core diameters of up to 50 µm. Bragg wavelength shifts depending on applied tensile strain as well as temperature changes are recorded and operating ranges of strain sensors identified. The ease of coupling with light sources into LMA fibers as well as their comparatively elevated robustness makes them promising sensor solutions for harsh environments.
