FIELD: quantum electronics.
SUBSTANCE: invention relates to quantum electronics and specifically to design of laser heads for solid-state lasers. LED optical pumping device for solid-state lasers containing LEDs, lenses and placed in laser gun, differs from known designs in that it comprises high-power LEDs arranged on laser head surface so that LED pumping source radiation is focused in active element location area by cylindrical lens to ensure required pumping radiation power density and laser radiation generation.
EFFECT: generation of laser radiation due to efficient absorption of pumping radiation from powerful light-emitting diodes which is focused on the active element by cylindrical optical elements.
