The Pound-Drever detector PDD 110 serves to lock a diode laser to the frequency of maximum absorption or transmission of a reference medium, e.g. an atomic transition or an optical resonator. The PDD 110 features an internal HF modulation source with variable output amplitude. The diode laser is modulated and the modulated signal after the reference medium is detected by an external photo diode. In the phase detector section of the PDD 110, the photo diode signal is mixed with the internal HF signal. The Pound-Drever error signal is derived from the phase delay of the modulated light. The bandwidth of the PDD 110 output signal is high enough to allow the use of the device even with very high-finesse resonators. |
