ABSTRACT:
A laser energy transmission optical fiber having an optical fiber main body which has a hollow-core region with a diameter greater than a wavelength of transmitted light, an inner clad region which has a solid portion with plurality of holes formed therein, and an outer clad region formed surrounding the inner clad region. The outer clad region has a refractive index lower than the solid portion of the inner clad region.
