Abstract :
Recent studies have shown the feasibility of a Cs maser without population inversion based on the coherent population trapping phenomenon. Among the main advantages of this type of frequency standard are size, simplicity of implementation, virtual absence of first order light shift and the availability of a low noise microwave signal leading to the realization of a standard with an excellent short term frequency stability.
