We demonstrate the ultra-stable frequency sources aiming to improve the short-time instability of primary frequency standards.These sources are realized by using photonic generation approach,and composed of ultra-stable lasers,opticalfrequency-combs,optical signal detecting parts,and synthesizers.Preliminary evaluation shows that the sources produce fixed-frequency at 9.54(/9.63) GHz,10 MHz,and tunable-frequency around 9.192 GHz with relative frequency instability of 10-15 for short terms.
