Abstract

To develop laser spectroscopy in the vacuum ultraviolet (VUV) region, a simple wavelength conversion technique with wavelength- and polarization-controllability is needed. We demonstrated that third harmonic (TH) generation at arbitral wavelengths between 146 nm and 190 nm can be achieved by using a dielectric free-standing thin film (nanomembrane) as a nonlinear medium. Furthermore, by using a photonic crystal nanomembrane with square-lattice periodic nanoholes, we observed the circularly-polarized TH light at 157 nm. The observed intensity of VUV light can be applied to VUV spectroscopy, and the photonic crystal nanomembrane is a promising new tool for wavelength conversion to vacuum ultraviolet.
