چکیده:

In this paper, we study the emitted light of the dipole nanolaser proposed by Protsenko et al. [Phys. Rev. A 71, 063812 (2005)] with attention directed to noise source by using of quantum Langevin formulations. with the steady state solutions, threshold condition for the lasing operation, spectrum of the intensity of the light, spectral line width and the number of the photon emitted are considered. Photon this light has a very wide frequency range, but for specific materials, line width can be reduced than to line width of the NP. Flux emitted by the DNL compare with that of an ordinary laser
