FIELD: physics.
SUBSTANCE: dipole nanolaser for generating coherent electromagnetic radiation includes a two-level system in form of a quantum dot and a coherent electromagnetic radiation resonator. The resonator, which has a metal or semiconductor nanoparticle and electrocontact plates, has one more nanoparticle which lies from the said nanoparticle and from the said quantum dot at distances less than wavelength of the coherent electromagnetic radiation generated by the said nanolaser. Both nanoparticles are capable of exciting dipole oscillation modes in antiphase at the frequency of the said coherent electromagnetic radiation.
EFFECT: higher Q-factor of the resonator of the dipole nanolaser.
