Available in PDF, EPUB and Kindle. Book excerpt: The first measurements of the effect of the focal intensity on the fidelity of phase conjugation in focused stimulated Brillouin scattering (SBS) are reported. Regardless of the strength of aberration, laser beams with focal intensities above 5 times the SBS threshold were conjugated accurately. As the focal intensity declined below this value, the phase conjugate fidelity declined. The maximum correctable aberration strength was that which reduced the focal intensity to near the SBS threshold. Higher laser powers corrected stronger aberrations. The pump laser was a single axial mode, tripled, Q-switched Neodymium:YAG, with a 6 nm pulse-width, operating at 355 nm. A computerized far-field image analysis system directly measured the focal intensity reduction due to aberrations. The focal intensity of the brightest far-field spot controlled both the reflectivity and the fidelity. A pair of laminar airflow, hot-wire array aberrators provided continuously variable, nearly sinusoidal phase modulation in the transverse axes. Lateral shearing interferometry and energy in the bucket measurements gave the Strehl ratio of the backscattered (reconstructed) beam, and hence the phase conjugate fidelity. A phenomenoligical theory for the phase conjugate fidelity of focused SBS was developed using resonator boundary conditions and a Gauss-Hermite mode decomposition. Analytical solutions for the case of no pump depletion were in qualitative agreement with the data.

Available in PDF, EPUB and Kindle. Book excerpt: Stimulated Brillouin scattering (SBS) is the most important example of a stimulated scattering process-light scattering that occurs when the intensity of the light field itself affects the propagating medium. A phenomenon that has been known of for some 35 years in solid state laser research, it has recently become relevant in the optical fiber ind

This book was released on 2005 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of the stimulated Brillouin scattering (SBS) was carried out by performing optical phase conjugation in open cells and multimode optical fibres using a Q-switched, pulsed Nd:YAG laser. Experiments were done with test tubes that contained two SBS liquids - Fluorinert and Acetone, and multimode optical fibres. The three fundamental parameters of SBS: the threshhold energy, reflectivity and phase conjugate fidelity were characterised and analysed. In addition, the temporal behaviour of Stokes beam, phase correction, optical beakdown, and pulse compression were investigated. --p. vii.

We chose not to await the maturation of the field, but instead to provide this material in time to be useful in its development. We have tried very hard to elucidate and interrelate the various nonlinear phenomena which can be used for optical phase conjugation.
