In this paper, two-color lasing emission is experimentally demonstrated by employing a multimode Fabry-Pérot laser diode (MMFP-LD) associated with external cavity of two tunable filters and an erbium-doped fiber amplification (EDFA), whose difference frequency is quasi-continuously tunable from several hundred GHz to more than 2 Gun Slings T
