Claim 31:
32. An illumination system comprising:
a light source configured to produce light in which a portion of the light from the light source has a wavelength from 440 nm to 2000 nm; and
a light-diffusing element comprising:
a glass core having a first refractive index and a longitudinal axis defining a length of at least 30 m;
a cladding surrounding the glass core along the longitudinal axis, the cladding having a second refractive index that is less than the first refractive index of the glass core; and
a coating surrounding the cladding, the coating including first scattering centers;

wherein the light source is optically coupled to a light-diffusing element;
wherein light from the light source having wavelength of 2000 nm has a first scattering intensity, wherein light from the light source having a wavelength of 440 nm has a second scattering intensity; and
wherein the first scattering intensity is within 5% of the second scattering intensity over a length of at least 30 m of the light-diffusing element.
