Experimental Properties of an Inhomogeneously Broadened He-Xe Unstable Ring Laser.
Abstract
Although the ring resonator has been previously investigated in several ways, the unstable ring resonator with imhomogeneously broadened gain medium is not yet well understood. The objective of this thesis is to explore reverse mode suppression in an unstable ring resonator by using a helium-xenon (He-Xe) gas mixture which is inhomogeneously broadened. The optical feedback technique employing a suppressor mirror was used. Several aspects of the unstable ring resonator are discussed: the relative power levels in forward and reverse waves, with and without the suppressor mirror, with strong and weak couplings from reverse wave to forward wave; the near field and far field patterns; and the mode volume effect. The degree of suppression in the reverse wave and the degree of increase in the forward wave, when the suppressor mirror was in place, are also discussed. (Author)
