High stability in near-infrared spectroscopy: part 2, optomechanical analysis of an optical contacted V-shaped cavity

Abstract Optical feedback is a powerful technique to stabilise and narrow semi-conductor lasers. As step forward for field deployable, ultra-stable yet tunable sources, we analyse model the opto-mechanical design of V-shaped cavity optical (VCOF) reference cavity. We estimate relative contributions sources external disturbance on resonance frequency cavity, ultimately define minimal thermal mechanical shielding requirements face conditions. attest robustness developed system, show that are only secondary contributors overall stability The suite analytical tools in process paves way lighter more compact designs, adapted deployment.
