| Abstract: | The factors affecting the wavelength of Laser Diode(LD) were presented.A circuit for wavelength precisely stabilization was designed and realized for coherent population trapping atomic clock.Experiment tests showed that the wavelength could be stabilized within 0.02 degree C by the circuitry.Corresponding wavelength control accuracy was 0.001 2nm. |
