Magnetic measurements on micron-size samples under high pressure using designed NV centers
Margarita Lesik, Thomas Plisson, Loïc Toraille +9
Pressure is a unique tool to tune the interplay between structural, electronic and magnetic interactions. It leads to remarkable properties of materials such as recent temperature…
Ultra-low noise dual-frequency VECSEL at telecom wavelength using fully correlated pumping
Hui Liu, Grégory Gredat, Syamsundar De +7
An ultra-low intensity and beatnote phase noise dual-frequency vertical-external-cavity surface-emitting laser is built at telecom wavelength. The pump laser is realized by polariz…
Noise investigation of a dual-frequency VECSEL for application to Cesium clocks
Hui Liu, Grégory Gredat, Ghaya Baili +4
We theoretically and experimentally study the noise of a class-A dual-frequency vertical external cavity surface emitting laser operating at Cesium clock wavelength. The intensity…
Rotation measurements using a a resonant fiber optic gyroscope based on Kagome fiber
A. Ravaille, G. Feugnet, B. Debord +4
We build a resonant fiber optic gyro based on Kagome hollow-core fiber. A semi-bulk cavity architecture based on a 18-m-long Kagome fiber permits to achieve a cavity finesse of 23…
Phase evolution of the direct detection noise figure of a nondegenerate fiber phase sensitive amplifier
Tarek Labidi, Ihsan Fsaifes, Weilin Xie +3
We experimentally investigate the evolution of the direct detection noise figure of a non degenerate phase sensitive amplifier based on nonlinear fiber, as a function of the relati…
Fully-correlated pumping for dual-frequency VECSELs dedicated to cesium CPT clocks
G. Gredat, D. Chatterjee, G. Baili +4
We report a fully-correlated multi-mode pumping architecture optimized for dramatic noise reduction of a class-A dual-frequency Vertical External Cavity Surface Emitting Laser (VEC…
