MODULATED LIGHT SOURCE |
| 摘要 |
A modulated light source includes an FP laser that emits light in a plurality of Fabry-Perot (FP) modes, a band-pass filter whose center wavelength can be modulated, a light reflector that selectively feeds only light having passed through the modulation filter back to the FP laser, and a wavelength adjustment mechanism that adjusts the center wavelength so as to coincide with one of the predetermined FP mode when the light fed back to the FP laser is used as seed light for stimulated emission of radiation to cause selective light emission at an oscillation wavelength. |

1. A modulated light source comprising:
an FP laser that emits light in a plurality of Fabry-Perot modes; a band-pass filter whose center wavelength can be modulated; a light reflector that selectively feeds only light having passed through the modulation filter back to the FP laser; and a wavelength adjustment mechanism that adjusts the center wavelength so as to coincide with one of the predetermined Fabry-Perot modes when the light fed back to the FP laser is used as seed light for stimulated emission to cause selective light emission at an oscillation wavelength. |
