Can Bessel beams be realized in the ultrabroad terahertz frequency range? - EurekAlert

The research team has been working on the generation and the manipulation of terahertz radiation from laser-plasma sources for many years. “THz radiation with Bessel beam profiles may be particularly interesting for medical and biological imaging” said Zhelin…
