FIELD: physics.
SUBSTANCE: converter has a basic element which is a system of two tunnel-linked quantum dots (QD) - a quantum molecule, which is doped with D- - and A+ - centres with QD based on GaAs with radii of 20 nm and 200 nm, respectively, with confinement potential amplitude of 0.2 eV and two-photon pumping wavelength λ=80 mcm.
EFFECT: possibility of adjusting laser generation wavelength from the infrared region to the visible light region.
