Abstract:
1. A system comprising: one or more elongated fibers, each of the one or more elongated fibers comprising a respective diameter; one or more optical components for at least one of conveying coherent light and interacting with the coherent light; and, an airflow device arranged to flow air over, and about perpendicular to, the one or more elongated fibers at a velocity, a combination of the respective diameter of each of the one or more elongated fibers and the velocity of the air configured to cause the one or more elongated fibers to produce shedding vortices that cause the one or more elongated fibers and the one or more optical components to each vibrate; wherein the respective diameter of each of the one or more elongated fibers and the velocity of the air meet a condition of: St*V/D≧100 Hz where V is the velocity of the air, D is the respective diameter of each of the one or more elongated fibers, St is a Strouhal number, and 100 Hz is a shedding frequency.
