Disclosed is a method for representation of visual or cognitive information by means of semiconductor lasers and solid-state diode-pumped lasers. The projection of letters, digits, logotypes, symbols is performed by device in which structure solid-state diode-pumped green light lasers (501-561 nm), and/or diode-pumped and semiconductor blue light lasers (450-473 nm), and/or red light lasers (620-671 nm) are used.
