  • Optical device for addressing a slave cavity with a wide-band laser source
    Patent number: 8098697
    Abstract: The invention concerns an optical device comprising an optical source for emitting a light beam in a plurality of emitting wavelengths and at least one laser, each of said at least one laser including a holographic medium (MH), means for injecting (FO, MCS, MUX, CO, IO, AV) said light beam derived from said optical source into said at least one laser, said holographic medium (MH) being adapted to generate a laser in at least one oscillation mode, said at least one oscillation mode being determined by at least one excitation wavelength among the plurality of emitting wavelengths. The invention is characterized in that said optical source comprises a light source emitting simultaneously in said plurality of emitting wavelengths.
    Type: Grant

  • Tunable laser source with optical wavelength addressing
    Patent number: 7519092
    Abstract: An optical apparatus including a tunable master laser from which all or some of a beam is injected into at least one “slave ” laser having a cavity with an amplifier medium and a dynamic holographic medium that forms a self-adapted spectral filter to maintain oscillation of the slave laser at a wavelength imposed by the master laser during injection after injection has stopped.
