ABSTRACT:
A laser radiation source apparatus comprises a laser source means for producing laser radiation; a stepped-index optical fiber; first coupling means for coupling the laser source means with one end of the stepped-index optical fiber; and second coupling means for coupling the other end of the stepped-index optical fiber with another fiber suitable for transmission of laser radiation. The stepped-index fiber optic includes a core suitable for transmission of laser radiation, which is encompassed by at least one cladding layer and a buffer layer, in which the refractive index value for the core is greater than the refractive index value for the cladding layer, and the refractive index value for the cladding layer is greater than the refractive index for the buffer layer, so that laser radiation transmitted into the cladding layer is transmitted through the fiber. Single index fibers having several diameters may be coupled to the apparatus.
