Study of filamentation threshold in zinc selenide

Abstract : The possibility of creating filaments with laser wavelengths ranging from 800 nm to 2.4 µm was investigated using an OPA laser system. Zinc Selenide's (ZnSe) unique characteristics – small band gap 2.67 gZnSe E e V = and positive dispersion for this wavelength range – are well suited for filamentation study where multi-photon absorption can be achieved with two to six photons.
