Abstract :
New readout configurations for a Fabry-Perot resonator that combine the reflected and transmitted waves are analyzed. The waves maybe combined in a Sagnac or Mach-Zehnder (MZ) configuration and tuned to a dark port to suppress the carrier frequency. Both the Sagnac and MZ schemes are analyzed in detail. Suppressing the carrier minimizes the shot noise floor of a Pound-Drever-Hall (PDH) frequency stabilized laser. Moreover, it is shown that a large improvement in frequency noise can be achieved for high power PDH stabilized lasers utilizing only a small phase modulation index
