| 英文摘要 | PURPOSE:To increase the efficiency of incidence coupling of laser light with a fiber type light wavelength converting element by conforming the elliptic spot of the laser light on a core end surface to the circular contour of the end surface. CONSTITUTION:The light wavelength conversion module 5 consists of a light wavelength converting element 10, the convergence optical system 20 composed of a collimator lens 21 and a condenser lens 22, and a semiconductor laser 30 as a basic wave generating means. The sectional shape of the core of the light wavelength converting element 10 is formed in an elliptic shape almost similar to the far visual field image of the laser light 15 emitted by the semiconductor laser 30, and the semiconductor laser 30 and convergence optical system 20 are arranged so that the beam spot on the core section 11a almost conform with the contour of the core section 11a. Therefore, the laser light 15 is projected on the core end surface by a proper quantity. Consequently, the efficiency of the incidence coupling of the laser light with the light wavelength converting element is increased. |
