  text: We unveil a powerful method for the stabilization of laser injection locking
    based on sensing variations in the output beam ellipticity of an optically seeded
    laser. The effect arises due to an interference between the seeding beam and the
    injected laser output. We demonstrate the method for a commercial semiconductor
    laser without the need for any internal changes to the readily operational injection
    locked laser system that was used. The method can also be used to increase the
    mode-hop free tuning range of lasers, and has the potential to fill a void in
    the low-noise laser industry.

  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.
