Solid-state laser compensated for pumping-light astigmatism |
August 17, 2004 |
| In a solid-state laser in which a gain crystal is polished to have the Brewster angle or a solid-state laser comprising a dichroic concave mirror to which light enters at an incidence angle which is not zero, astigmatism generally occurs in pumping light. By tilting a focusing lens for p |

Solid-state laser and optical transmitter |
June 22, 2004 |
| A solid-state laser having an excitation light source, a lens system for focusing an excitation light produced from the light source, and a laser resonator which is laser-oscillated in response to the focused excitation light. The resonator includes only a gain medium and a solid-state m |

Optical interferometer and signal synthesizer using the interferometer |
July 1, 2003 |
| An optical signal synthesizer having an optical slab waveguide constructed from three layers in which optical pulses are introduced. A first cut-away portion of the optical slab waveguide has a plano-concave shape serving as a plano-convex lens which collimates the introduced optical pul |

Solid-state laser and optical transmitter |
May 6, 2003 |
| In the wavelength-division-multiplexed optical transmission, laser diodes of the number of multiplicity are disposed as a light source to configure a transmitter. However, since this method requires a large number of light sources and highly precise wavelength control, a cost and an appa |

Solid-state laser compensated for pumping-light astigmatism |
May 14, 2002 |
| In a solid-state laser in which a gain crystal is polished to have the Brewster angle or a solid-state laser comprising a dichroic concave mirror to which light enters at an incidence angle which is not zero, astigmatism generally occurs in pumping light. By tilting a focusing lens for p |

Compact solid-state laser and transmitter using the same |
October 23, 2001 |
| A compact solid-state laser has its cavity formed by the reflection surface of a gain crystal and the reflection surface of a chirped mirror. The pumping light is incident to the cavity through the reflection surface of the gain crystal or the chirped mirror, from which the laser output |

Optical interferometer and signal synthesizer using the interferometer |
July 18, 2000 |
| A femtosecond pulse incident on a Mach-Zehnder interferometer is divided into two optical paths and thereafter synthesized again. The synthesized optical pulse is outputted as complementary two output optical pulses corresponding to the difference between optical paths. An optical in |
