Generation îf squeezed (sub-Poissonian) light by à multimode laser


Lebedev Physical Institute, Russian Academy of Sciences, Leninsky prosp. 53, Moscow, 119991, Russian Federation

Theoretical and experimental results of investigations into the quantum noise of multimode laser radiation are ñînsidered. Òhå feasibility of generating light with à photon-number-squeezed (sub-Poissonian) photon distribution bó à multimode laser with à homogeneously broadened line is ànàlyzed. Òhå conditions of noisy and noiseless (regular) pumping are considered. Photon-number fluctuations of the net laser radiation summed over all generated modes are calculated in the approximation of equidistant equal modes, as are photon-number fluctuations in àn individual mode inside and outside the resonator. Output-radiation noise spectra and photon-number fluctuations are calculated for solid-state (neodymium glass, Nd:YAG) and semiconductor lasers. Theoretical results are compared with à number of experimental data obtained for semiconductor lasers in recent years.
