Compact, Portable, Thermal-Noise-Limited Optical Cavity with Low Acceleration Sensitivity
We develop and demonstrate a compact (less than mL) portable
Fabry-P\'{e}rot optical reference cavity. A laser locked to the cavity is
thermal noise limited at fractional frequency stability.
Broadband feedback control with an electro-optic modulator enables near
thermal-noise-limited phase noise performance from Hz to kHz offset
frequencies. The additional low vibration, temperature, and holding force
sensitivity of our design makes it well suited for out-of-the-lab applications
such as optically derived low noise microwave generation, compact and mobile
optical atomic clocks, and environmental sensing through deployed fiber
networks.Comment: 12 pages, 6 figure
