ABSTRACT:
A wavelength converting device is constructed by: a fiber type wavelength converting device which uses the Cerenkov radiation type phase matching and comprises a non-linear optical crystalline core and a clad; and a transparent resin portion surrounding the wavelength converting device, wherein the resin portion has a resin outgoing edge surface of a large enough size such that the entire second harmonics light is emitted from the outgoing edge surface. The above device is a light-wavelength converting device having long enough operation length and a high conversion efficiency and is a device having an excellent environmental resistance and a high coupling efficiency.
