Abstract:
A spark delivery system (100) for generating a spark using a laser beam (102) is provided, and includes a laser light source (104) and a laser delivery assembly (108). The laser delivery assembly (108) includes a hollow fiber and a launch assembly comprising launch focusing optics to input the laser beam in the hollow fiber. The laser delivery assembly (108) farther includes exit focusing optics that demagnify an exit beam of laser light from the hollow fiber, thereby increasing the intensity of the laser beam and creating a spark.
