Tunable Two-Color Lasing Emission Based on Fabry-Pérot Laser Diode Combined With External Cavity Feedback
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), Medical and Ambulatory supplies / Needles and Syringes whose difference frequency is quasi-continuously tunab
