ABSTRACT:
A method positions a first end of an optic fiber a distance from a target and applies a laser light to a second end of the optic fiber such that the laser light is guided by the optic fiber from the second end to the first end of the optic fiber and is emitted from the first end of the optic fiber toward the target as a beam of light. The beam of light has a first area of incidence at the target. The optic fiber is then bent such that the beam of light continues to reach the target and such that the area of incidence of the beam of light at the target changes without changing the distance between the first end of the optic fiber and the target. A device having two plates with raised portions inside a metal case is provided for bending the optic fiber.
