Theoretical and Experimental Investigations of Saturation Effects in a Gas Laser


Maeda, Hisatoshi (1973) Theoretical and Experimental Investigations of Saturation Effects in a Gas Laser. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/K70K-GS53.


Theoretical studies of standing and traveling wave lasers are presented. The spectral behavior of the amplified spontaneous emission (superradiance) in a pencil-shaped column is investigated theoretically and experimentally. Spectral narrowing followed by rebroadening has been observed as predicted by the theory.

A geometrical representation of an interacting two-level atomic system has been developed and applied to an optical laser. A semi-classical model for a standing wave laser has been examined using the rotating wave approximation, and compared to the exact solution. Depth and width of the Lamb dip are determined theoretically and experimentally. The effect of radial profile of the laser field has been studied using the self-consistent-field approach, and the radius of the beam was measured at various positions from the window.
