  text: Lasers with well-controlled relative frequencies are indispensable for many
    applications in science and technology. We present a frequency-offset locking
    method for lasers based on beat-frequency discrimination utilizing hybrid electronic
    LC filters. The method is specifically designed for decoupling the tightness of
    the lock from the broadness of its capture range. The presented demonstration
    locks two free-running diode lasers at 780 nm with a 5.5-GHz offset. It displays
    an offset frequency instability below 55 Hz for time scales in excess of 1000
    s and a minimum of 12 Hz at 10-s averaging. The performance is complemented with
    a 190-MHz lock-capture range, a tuning range of up to 1 GHz, and a frequency ramp
    agility of 200kHz/μs.
