| Zusammenfassung | Quantum fluctuations in a radiation of multitransverse-mode laser are investigated theoretically and numerically, based on quantum c-number langevin stockastic equations for the complex amplitudes of transverse modes. It is shown that strong antiphase quantum fluctuations of transverse-mode amplitudes occur, which corresponds to spatial fluctuations of the laser field. Fluctuation spectra are calculated, showing that antiphase fluctuations dominate at low frequencies (smaller than relaxation oscillation frequency), and in-phase oscillations prevail at high frequencies. |
