Abstract

A new technique for sensing optical cavity mode mismatch using a mode converter formed from a cylindrical lens mode converting telescope, radio frequency quadrant photodiodes (RFQPDs), and a heterodyne detection scheme. The telescope allows the conversion of the Laguerre-Gauss basis to the Hermite-Gauss (HG) basis, which can be measured with quadrant photodiodes. Conversion to the HG basis is performed optically, measurement of mode mismatched signals is performed with the RFQPDs, and a feedback error signal is obtained with heterodyne detection.
