  • Wavelength tunable laser and optical tomography system using the wavelength tunable laser
    Patent number: 8204088
    Abstract: An external resonator type wavelength tunable laser has a laser medium, a dispersion system which spatially disperses light emitted from the laser medium by wavelength, and a wavelength selecting system having a reflecting surface which selectively reflects a part of the light which is reflected by the reflecting surface as a return light, and the wavelength selecting system is structured so that the inverse of a number of a wavelength of the return light linearly changes with time.
    Type: Grant
    Filed: March 22, 2007
    Date of Patent: June 19, 2012
    Assignees: FUJIFILM Corporation, Fujinon Corporation
