Abstract: We present further development of our solutions of attractive Interference Wedged Structure based Beam Splitters built as suitable composition of only pure glasses (using Fresnel's reflection). Theoretical treatment and experimental test show the potential for suitable parameters to reach controlled splitting in range of 26%-99%. The splitters are list-like (5x2x0.2cm) interferential constructions especially for laser light. No problematic dielectric and metallic mirrors, operating power MW/cm2, easily maintenance. We have developed, applied and improved theoretical model for description and computer treatment.
