Ramsey CPT Signal Generation with a Miniature Clock Bench and a Dual-Frequency Optical Generator
Stéphane Guérandel, Jérémie Cotxet, François Gutty +4
We demonstrate, for the first time, Ramsey CPT spectroscopy with a miniature electro-optical bench associated to a dual-frequency generator based on combined optical injection lock…
Optimization of laser dynamics for active stabilization of DF--VECSELs dedicated to cesium CPT clocks
Grégory Gredat, Hui Liu, Jérémie Cotxet +5
We report the implementation and performance of a double servo-loop for intensity and phase-difference active stabilization of a dual-frequency vertical external--cavity surface-em…
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…
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…
Excess noise factor in non-Hermitian mode-locked lasers
Oriane Lelièvre, Khadija Abensar, Ghaya Baili +3
We predict and observe the appearance of an excess noise factor due to the non-Hermiticity of the modes of two actively harmonically mode-locked lasers. The non uniform distributio…
