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.
