1. the method for a driving laser diode may further comprise the steps:

  • Produce a pre-drive signal;

    Produce a main drive signal;

    Wherein said pre-drive signal is formed and makes the levels of current of said pre-drive signal remain on the one period duration an of value that is equal to or higher than the laser diode current threshold value;

    Make that the quantity of the charge carrier that injects in the said laser is near equilibrium level before applying said main drive signal;

    AndSaid pre-drive signal and said main drive signal are applied to said laser diode, and wherein said pre-drive signal alleviates the spike effect in the laser optical output.
