Interference of intensity noise in a multimode Nd:YAG laserHill, Timothy J. January 2003 (has links) (PDF)
Includes bibliographical references (leaves 151-163). Investigates the behaviour of the intensity noise in a multimode Nd:YAG laser. The collective modes of oscillation are excited by broadband ambient noise. Because the phase of the excitation is unknown, a cross spectral technique to measure the antiphase dynamics directly and form a picture of the intensity noise interference for two to five mode operation is developed. For three mode operation, the contributions of the longitudinal modes to collective modes is measured.

Antiphase dynamics in solid state lasers with Fabry-Perot cavity / by Laurentiu Stamatescu.Stamatescu, Laurentiu January 2003 (has links)
Bibliography: leaves 154-156. / 156 leaves : ill. (some col.) ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / This thesis describes the construction of a low-power end pumped Nd:YAG laser and the subsequent theoretical and experimental investigation of the antiphase dynamics exhibited by the laser. The end pumped laser was modelled by extending the classical model of Tang Statz deMars to non-uniform pump along the active medium. The anomalous threshold behaviour of the laser, where modes with lower gain can supass modes with higher gain as the pump power increases, was accounted for. The antiphase dynamics were explored by modulating the pump power and measuring the transfer functions from this input to various outputs. The laser's response to various sources of noise was also studied. / Thesis (Ph.D.)--University of Adelaide, School of Chemistry and Physics, Discipline of Physics and Mathematical Physics, 2003?
