| Research Abstract |
Spherical Raman lasers and Nd^<3+>-doped lasers of multi-wavelength emission (50-100 wavelengths) were developed through the following techniques : (1) Terrace formation on the surface of high refractive-index glass spheres, (2) pumping and read-out by optical fiber couplers. Selection of pumping wavelength with a CW Ti : Sapphire laser enables us to find "the Raman enhancement effect" between Raman scattering and Nd^<3+> fluorescence. Using the optical fiber couplers and terrace microsphere, directional pumping and read-out will be possible.
