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 THz. The obtained side-mode suppression ratio (SM... https://www.markbroyard.com/flash-offer-36-meter-4-teilige-interlock-ettore-rea-c-h-teleskopstange-for-sale-limited-save/
