FIELD: optics.
SUBSTANCE: group of inventions relates to laser equipment. Device implementing a method for projecting images with laser brightness enhancement comprises a laser active element with a pumping system, on one side of which the projected object and the focusing optical system are located, and on the other side the projection lens. At least one laser active element with a pumping system is additionally installed between the laser active element and the projection lens. In addition, a time synchronization block for excitation of laser active elements coupled with their pump systems has been introduced.
EFFECT: technical result consists in increasing the brightness and contrast of the projected image.
