According to ref.4, the radius of the sharpest THz light ring can be expressed asR=ftan(arcsin(nsinα)−α),R=ftan(arcsin(nsinα)−α),(1)where α and n is the base angle and the refractive index of the Teflon axicon, f is the focal length of the silicon lens. Herein, these parameters are α = 20°, n = 1.42618, f = 8 mm, respectively. The calculated R equals 1.29 mm,......阅读全文
