| 英文摘要 | PURPOSE:To simultaneously stabilize a multiplicity of light source frequencies by a method wherein optical signals of various frequencies are directly and simultaneously put into a sweep-type interferometer, the output of the interferometer is detected by a photodetector, and differences between the optical frequencies are determined from a stabilized optical frequency. CONSTITUTION:The output of an optical fiber F16 travels through a lens L11 and then a Fabry-Perot etalon 30, and is coupled to a photodiode D11 by a lens L12. The fluctuation in optical frequency in a semiconductor laser 11 is converted into an optical intensity fluctuation by the etalon 30 and then into a signal intensity fluctuation by the photodiode D1 The signal intensity fluctuation is negatively fed back to the semiconductor laser 11 through a current control circuit 31, for the optical frequency to be absolutely stabilized. The output of a wave combining unit 29 travels through an optical directional coupler C12, optical fiber F19, lens L13, and then a sweep-type Fabry-Perot interferometer 32, to be coupled to a photodiode D12 by a lens L14 for direct detection. The output then travels through an A.D converter 33, and a processor 34 determines the relative differences between optical frequencies f12, f13, f14 and optical frequency f11, respectively. The differences are negatively fed back, respectively, to semiconductor lasers 22, 23, and 24 through a scanner 45 and D.A converter 36. |
