Paper Abstract

Towards the development of new optical fiber sensors it was studied the application of nanosecond infrared laser radiation in the micropatterning of optical fibers. Nd:YAG laser pulses were focused on silica fibers by an apparatus projected to position the fiber regarding the laser beam and analyze the interaction. Experiments allowed determining the conditions to vaporize the required amount of material. Holes with few microns and depths higher than 10 microns were accomplished with multiple shots and advancing the fiber regarding the beam's focus. The results analysis demonstrated the possibility of obtaining patterns and the technique potential in the development of fiber sensors.
