Beam Combining via Orientational Stimulated Scattering: Numerical Modeling and Analytic Solutions

Abstract

Many present-day solid-state lasers can generate very large CW power, especially in the regime of Master Oscillator Power Amplifier (MO-PA) scheme. The task of combining individual beamlets into one high-power beam of diffraction quality is therefore quite important. One of the ways of beam combining and clean-up has been suggested recently 1. It is based on the use of Stimulated Orientational Scattering in a Nematic Liquid Crystal (NLC) 2, 3. The present work is devoted to the development of numeric and analytic tools of study of such beam combining. One-dimensional (+ time) model of orientational scattering is based on the system of coupled wave equations for amplitudes A and B of waves of two polarizations:
