Advanced Layout for R/W Beam Expander Using Dual Polarization Techniques

This document outlines a novel layout featuring two orthogonal polarizations for the R/W beam expander system. The design permits independent operation of the system components. Each slave (SL) section may require the addition of an expander to optimize performance. The layout diagrams indicate the polarization for the blue (R/W beam) and cyan (guiding beam). This advanced configuration, suitable for patent application, includes details on actuators, guiding beams, and polarization beam splitters (PBS), facilitating enhanced functionality and efficiency in optical applications.
