Laser-microcavity relative frequency fluctuations caused by thermal locking are studied. The locking of laser-microcavity detuning causes microcavity temperature fluctuations that transfer pump frequency noise onto the microcavity modes within the thermal locking bandwidth.
High-Q disk resonators are used to frequency stabilize two fiber lasers. The improved phase noise of the devices is measured by heterodyne detection and compared to theoretical limits set by thermo-refractive noise.
We generate 10 GHz microwave signals from high quality factor (Q∼1011) optical resonators via optical frequency division. The demonstrated phase noise is comparable to or better than that obtained via cryogenic systems for timescales < 1s.
