Characterization and transformation of Terahertz Bessel beams with angular orbital momentum
- Mrs. Natalia OSINTSEVA
- Ms. Yulia CHOPOROVA
Recently, using silicon binary axicons with spiral zones, we transformed a NovoFEL Gaussian beam into Bessel beams with orbital angular momenta l = ±1 and l = ±2. In this paper we study the propagation of beams through random mediа and investigate optical systems which allow extending the length of non-diffractive beam propagation.
