Method and device for stabilizing the emission wavelength of a laser |
摘要 |
A process and device are provided for stabilizing the emission wavelength of an optical source (1), which emits radiation at a first wavelength, by locking to the emission wavelength of an optical reference source (2) which emits radiation at a second wavelength which is substantially different from the first. The stabilization device applies to the source to be stabilized a feedback signal obtained by detection of an optical beat between the two radiations. A two-photon absorption for the first wavelength is used to generate the beat. <IMAGE> |
