Abstract
Single beam signal (SBS) components of the laser intensity monitor (LIM) signal are blanked from the path length control circuit (PLC). The AC component of the LIM signal, less the SBS components, is then integrated to produce a transducer mirror drive signal. SBS component blanking is synchronized to the dither pick-off signal. Peak power operation of the PLC is enhanced through the removal of the SBS components from the LIM signal.
