International audienceWe study the noise of a class-A dual-frequency vertical external cavity surface emitting laser at Cesium clock wavelength. Both the intensity noise and phase noise of the beatnote between the two orthogonal polarized modes are measured and modeled. The intensity noise of the two orthogonal laser modes and its correlation are well predicted by a theory based on modified rate equations. The phase noise of the beatnote is predicted by the theory based on thermal effect and phase/amplitude coupling effect
