The RF Modulation Spectroscopy Setup is able to generate a locking error signal on top of line of atomic reference gas spectra. This special preprocessed error signal stabilize the frequency of the emitted laserradiation in combination with the LB2001 and LB2005 and results in a frequency stabilized narrow linewidth of Sachers lasersystems.
