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

Download or read book Phase Conjugate Fidelity of Focused Stimulated Brillouin Scattering written by Lee Paul Schelonka and published by . This book was released on 1988 with total page 346 pages. 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.

Book excerpt: A Brillouin enhanced four wave mixing phase conjugate mirror corrects phase aberrations of a coherent electromagnetic beam and birefringence induced upon that beam. The stimulated Brillouin scattering (SBS) phase conjugation technique is augmented to include Brillouin enhanced four wave mixing (BEFWM). A seed beam is generated by a main oscillator which arrives at the phase conjugate cell before the signal beams in order to initiate the Brillouin effect. The signal beam which is being amplified through the amplifier chain is split into two perpendicularly polarized beams. One of the two beams is chosen to be the same polarization as some component of the seed beam, the other orthogonal to the first. The polarization of the orthogonal beam is then rotated 90.degree. such that it is parallel to the other signal beam. The three beams are then focused into cell containing a medium capable of Brillouin excitation. The two signal beams are focused such that they cross the seed beam path before their respective beam waists in order to achieve BEFWM or the two signal beams are focused to a point or points contained within the focused cone angle of the seed beam to achieve seeded SBS, and thus negate the effects of all birefringent and material aberrations in the system.
