Abstract

Diffractive optical elements (polypropylene kinoform diffractive lenses, silicon binary diffractive lenses, and silicon beamsplitters) for the terahertz spectral range have been designed and characterized using high-power terahertz radiation of Novosibirsk free electron laser. The effect of an antireflection coating on the silicon elements was studied.
