            Abstract : 
We report on the stabilization of the beatnote of a 1.5 mum dual-frequency laser using optical frequency locked loops (OFLLs). The principle of these OFLLs is based on an electro-optical frequency discriminator which contains one or two fiber-optic delay lines. The lowest phase noise, -107 dBrad2/Hz at 10 kHz for frequencies ranging from 2 to 6 GHz, has been obtained by combining two delays of 5 mus and 0.5 mus.
