A semiconductor laser is driven by a electrical circuit of gain switch, the variations of its pulse width and power vs bias current and driving pulse are studied. The optimal parameters are found. The shortest pulse width of this semiconductor laser is 26 ps. Also, using analytic?! model and numerical calculation, the experimental results are simulated successfully.
