The SK301 Vidourle RF Demodulator was primary designed for use in laser frequency stabilization applications where the frequency offset between the laser source and the optical reference requires tight and fast control. Indeed, when used in a Pound-Drever-Hall locking scheme, the SK301 provides a voltage related to the frequency offset under control. This error signal is further processed by an external compensator in order to drive the laser frequency actuator. The SK301 actually performs a phase sensitive detection of a photodetector output signal to translate its spectrum from the RF domain to a base-band error signal. In complement with this basic frequency mixer operation, the SK301provides the user with several useful functionalities in this specific context.
Like all modular instruments of the SK-Series, the SK301 RF Demodulator can be operated stand-
alone or within a platform where several modules can be assembled to configure a specific control
or measurement system. The SK301 can be thus coupled to the SK433 PI2D Compensator for high-
performance, closed-loop laser frequency control.
