GRADIOM - Gradiomètre de gravité à ondes de matière
To develop a new generation of highly efficient external enhancement-cavity doublers at 780 nm.
About the project:
The GRADIOM project is the following of the GRAVITER project, which led to the development of a new generation of highly efficient external enhancement-cavity doublers at 780 nm, which was later patented with Muquans.
The first step of the GRADIOM project consists to improve the optical performance of this doubler to 780 nm in order to obtain several watts and to enable multiphotonic Raman transitions and thus open the way for the implementation of atomic interferometers with a considerably increased area.
The second mission of this project is to use its skills to access shorter wavelengths, especially around 461 nm for strontium atom cooling applications.
The last part will be devoted to prospective studies to reach the area of ultraviolet around 390 nm or 399 nm.
Develop single-frequency laser sources by cavity-frequency doubling to access specific wavelengths of atomic transitions: 780 nm, 461 nm, 390 nm.
