Abstract
Fundamental nonlinear optical properties have been studied to understand the light-matter interaction. These properties are linear effects of Fluoresces and Absorption and Spontaneous Raman Scattering (SR), nonlinear effect of Stimulated Raman Scattering (SRS), Self-Phase Modulation (SPM), 4 wave effects, Second Harmonic Generation (SHG), and Optical Kerr Effect (OPE).

Experimental setup for SRS, SC, and Optical Kerr gate: A 517nm horizontally polarized laser pulse with 0.7μJ pulse energy was generated from a 1035nm laser pulse (282 fs pulse duration) with 26.2μJ pulse energy via SHG to study SRS, SPM. A Supercontinuum and SRS was observed. In addition, the identical laser pulses were used to build an Optical Kerr gate to determine the vibration lifetime of Carbon disulfide and to study the Ultrafast Kerr Young Double Slits Interference and Diffraction for fringe change in Liquid Carbon disulfide.
