Abstract
We present an innovative multi-line fiber laser system for both cesium and rubidium manipulation. The architecture is based on frequency conversion of two lasers at 1560 nm and 1878 nm. By taking advantage of existing high performance fibered components at these wavelengths, we have demonstrated multi-line operation of an all fiber laser system delivering 350 mW at 780 nm for rubidium and 210 mW at 852 nm for cesium. This result highlights the promising nature of such laser system especially for Cs manipulation for which no fiber laser system has been reported. It offers new perspectives for the development of atomic instruments dedicated to onboard applications and opens the way to a new generation of atom interferometers involving three atomic species (85Rb, 87Rb and 133Cs) for which we propose an original laser architecture.
Highlights
Atom interferometry has shown to be a powerful tool for precision measurements especially through the demonstration of high performance inertial sensors like gravimeters [1,2,3,4], gradiometers [5, 6] or gyroscopes [7, 8]
We propose an original laser architecture very promising for 85Rb, 87Rb and 133Cs atom interferometry
A phase modulator is inserted between the laser source and the Erbium-Doped Fiber Amplifiers (EDFA) to demonstrate the ability to generate additional laser lines necessary for instance during both atom cooling and interferometry phases
Summary
Atom interferometry has shown to be a powerful tool for precision measurements especially through the demonstration of high performance inertial sensors like gravimeters [1,2,3,4], gradiometers [5, 6] or gyroscopes [7, 8]. Cesium atoms are extensively used in a wide range of applications whether for commercial or research purposes, for instance for high performance magnetometry, atom lithography for nanofabrication, or in atomic clocks used as a primary frequency standard For such applications, a compact and reliable laser system at 852 nm is of prime importance and an all-fibered laser system could open new promising perspectives. A huge interest of working at the telecom wavelength comes from the availability of high quality fibered optical components such as fibered AOM’s for power control or fibered phase/intensity modulators for generating all the required laser lines for typical atom interferometer experiment, allowing the use of only a single fiber laser source [23]. We propose an original laser architecture very promising for 85Rb, 87Rb and 133Cs atom interferometry
