The PFD pro is a broadband phase and frequency detector that generates an error signal from the phase and frequency difference between two lasers. It offers user-friendly integration with TOPTICA lasers, control electronics, and software. PFD pro enables a complete solution in which two lasers are phase-locked to each other with an offset frequency that can easily be ramped or changed. Typical applications include the phase lock of an optical frequency comb to a continuous-wave reference laser, phase locks of lasers to an optical frequency comb, phase locks between two single-frequency lasers with large frequency offsets, frequency ramps and jumps for laser cooling sequences, and frequency scans for spectroscopy or the de-drifting of ultra-narrowband cavity-stabilized lasers.
