| 英文摘要 | PURPOSE:To provide the stable short wavelength light source of the SHG light output stable to temp. by providing a step in a part in the optical waveguide direction of a substrate, installing a collimator lens and focusing lens on this step and entering light into the optical waveguide via lenses. CONSTITUTION:This laser light source is provided with the LiNbO3 substrate 10 having a nonlinear optical effect, the collimator lens 14 which is provided in a part in the optical waveguide 11 direction of this substrate 10 and converts the light emitted from the laser light source to collimated beams of light and the focusing lens 15 which converges the collimated beams of light. The light is then entered into the optical waveguide 11 via these lenses 14, 15. Since the optical waveguide 11 and the lens system are effectively disposed on the same substrate 10, the coeffts. of thermal expansion and Young's moduli of the lenses 14, 15 and the optical waveguide 11 are fairly approximate as compared with the coeffts. of thermal expansion and Young's moduli of metallic systems and, therefore, the thermal distortions by temp. are decreased. The output of the wavelength converting element (SHG) light 17 stable to temp. is obtd. in this way. |
