Abstract
An example of a fiber optic light source has a pump laser that feeds light to a length of doped optical fiber. The optical fiber produces light that has a mean wavelength, for example in the range of 1515 nm to 1544 nm, such that the light is substantially unaffected when exposed to weapons level radiation.
