| 摘要 |
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.
