Frequency Stability of Spatial Mode Interference (Tilt) locking

Slagmolen, Bram; Shaddock, Daniel; Gray, Malcolm; McClelland, David


This paper describes the investigation of the frequency stability of tilt locking, a technique which derives an error signal for locking a laser to an optical cavity by use of spatial-mode interference. By independently locking two lasers to the same optical cavity and measuring the beat frequency, a direct measurement of the stability of tilt locking was obtained. The beatnote exhibited a normal Allan deviation of 3.3 Hz over a time interval of 100 ms, yeilding a relative frequency stability...[Show more]
