1. A method of producing high quality laser-induced images inside optically transparent materials by simultaneously generating breakdowns in two or more separate focused small points comprising the steps of:

  • determining right form and size of an etch point;

    determining optimal sizes of focal spots allocated inside etch point area;

    creating said etch points for production of a black-white image;

    creating etch points of the said form and size for production of an image gradation;

    generating a main laser beam having a main energy level;

    transforming and focusing said main laser beam into two or more separate small spots inside a transparent material area corresponding to the said etch point;

    etch point brightness control.
