| 英文摘要 | PURPOSE:To improve second harmonic generating efficiency by providing an external resonator for a crystal or a waveguide in hybrid or monolithic manner and causing resonance with primary coherent light. CONSTITUTION:Output light from a semiconductor laser 1 is collimated and transmitted through a half-mirror with transmittance of 5%, and a ring-type resonator is constructed from mirrors 2, 3, 4, 5. After the mirror 4, the laser light beam is led to a waveguide path 7 by a lens 6. Thus, the guided light radiates second harmonic wave to the substrate 8 side as a Cerenkov beam 9. On the other hand, the transmitted guided light is converged by a lens 10 and guided again to the waveguide path 7 via the mirrors 5, 2, 3, 5 to radiate the Cerenkov beam 9. Described process is repeated many times to enhance second harmonic radiation of the semiconductor laser so that second harmonic light output larger than several times the case of single bus can be obtained. |
