1. method that improves the laser operating efficiency of laser instrument (50), described laser instrument (50) optical data read and/or write device (10) in use, this method is characterized in that, may further comprise the steps:

  • A) produce pulse excitation signal with one or more pulse trains (690,720), its pulsed frequency substantially at 50MHz in the scope between the 250MHz;

    AndB) exciting current of described one or more pulse train (690,720) with modulation flowing through laser (50) is set, described pulse is across the laser threshold (650) of laser instrument (50).
