Laser Spectra, Tuning, and Stability

Polariton mechanism of condensation of the emission spectrum of a laser near an absorption line

V. V. Kocharovsky, Vl. V. Kocharovskii


Abstract: An investigation is made of the condensation of the emission spectrum of a multimode laser near a strong absorption line of an intracavity gas cell associated with a strong frequency dispersion of polaritons in a gas. It is shown that the polariton mechanism includes—in addition to the usual (in intracavity laser spectroscopy) change in the Q factor and, consequently, in the mode amplitudes—an increase in the density of polariton mode frequencies.
