In this paper, experimental results for a current modulation frequency locking scheme in a single feedback control loop are presented, and are compared with the Pound-Drever-Hall (PDH) topology. This experiment provides confidence that with proper pre-stabilization of the diode laser in a more sophisticated two-loop control scheme, current modulation may well attain similar ultra-resolution strain sensitivities as those achieved using the PDH technique.
