Manipulating stimulated‐emission processes and overcoming the ohmic loss of metals in plasmonic lasers are of significance for the according applications in biological sensors, data storage, photolithography, and optical communications. Herein, through utilizing an electrochemical‐assisted growth method for high‐quality perovskite nanowires, plasmonic lasers based on the structure of metal/dielectric layer/perovskite nanowires are constructed. The plasmonic lasers demonstrate a threshold of 62 µJ cm −2 , a high quality factor of Q ≈ 655, and a fast lasing decay time of 1.6 ps. Interestingly, the plasmonic lasers present an attractive capability in transformation from single mode to multiple modes just by adjusting the pumping energy. In addition to the broad stoichiometry‐dependent tunability of the perovskite materials, the proposed plasmonic lasers have great promise in real applications.
