Fiber coupled optical spark delivery system
Abstract
A spark delivery system for generating a spark using a laser beam is provided,
the spark delivery system including a laser light source and a laser delivery
assembly.
The laser delivery assembly includes a hollow fiber and a launch assembly
comprising
launch focusing optics to input the laser beam in the hollow fiber. In
addition, the laser
delivery assembly 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. In accordance with embodiments of the present invention, the assembly
may be
used to create a spark in a combustion engine. In accordance with other
embodiments
of the present invention, a method of using the spark delivery system is
provided. In addition,
a method of choosing an appropriate fiber for creating a spark using a laser
beam is also presented.
