Paper Abstract

The design and construction of a compact instrument that automatically measures Kerr-based third order nonlinearities (both nonlinear refractive index: γ, and nonlinear absorption: β) in materials, is presented. The instrument includes control of the polarization state of the input laser beam and was calibrated with well known reference samples. The mechanical translation system and the polarizer rotation-stage are controlled via a home-made electronic circuit, whereas the data acquisition from three photodiodes is performed by a National Instruments 12-bits DAQ. The entire system is fully controlled by means of an application program encoded in LabView. The importance of the developed experimental device is its reliability, compactness, easy implementation and transport, table-top installation, low cost and high accuracy.
