PROBLEM TO BE SOLVED : To provide a continuous wave supercontinuum laser source resonator using low-priced multimode semiconductor lasers as pumping light and applying a rare-earth doped optical fiber and a Highly Nonlinear Dispersion Shifted Fiber to a ring resonator structure to embody a continuous wave supercontinuum light source, and a medical diagnostic apparatus using the same. SOLUTION : The continuous wave supercontinuum laser source resonator is provided with a pump combiner for inputting pumping light into the resonator; a rare-earth doped optical fiber for receiving and converting the pumping light into seed light of a predetermined wavelength band; the Highly Nonlinear Dispersion Shifted Fiber for converting the light converted by the rare-earth doped optical fiber, and oscillating in the resonator into the continuous wave supercontinuum laser source; and a coupler for outputting the supercontinuum laser source generated from the Highly Nonlinear Dispersion Shifted Fiber. Accordingly, it is possible to embody a simple and inexpensive continuous wave supercontinuum laser source. COPYRIGHT : (C)2007, JPO&INPIT
