Single-Axis Transfer Cavity

The AOS-Cav-λ_R-λl is a non-confocal Fabry-Perot optical cavity in UHV for stabilization transfer from a reference laser with wavelength λ_R (e.g., rubidium-stabilized 780 nm laser) to disparate laser wavelengths (e.g., for atomic ion laser cooling) either by offset Pound-Drever-Hall locking or scanning transfer technique.  The target finesse is >1,000 for all wavelengths. Device includes electrical feedthrough/interface for PZTs, thermistor, and heating element for temperature stabilization.  An ion pump controller is not included.
