Femtosecond Kerr index of cyclic olefin co/polymers for THz nonlinear optics
Source abstract
Abstract
Abstract The second-order nonlinear refractive index n 2 (Kerr index) of cyclic olefin copolymer (TOPAS) and cyclic olefin polymers (ZEONEX, ZEONOR) was determined at the wavelength of 800 nm within this work. Bulk samples of ZEONEX, ZEONOR and TOPAS were measured using the single-beam Z-scan technique and the values of their nonlinear refractive index were determined to be approximately 2 × 10 −20 m 2 W −1 for all cases. The obtained values of n 2 play a vital role for ultrafast pulse evolution and corresponding phenomena such as nonlinear spectral transformation.
