“The Supercontinuum Light Source: Improved Methods of Generation and Spectroscopic Use” By investigating the physical relationships between various optical and material parameters, we achieve dramatic enhancement of optical nonlinearities during laser pulse propagation in photonic crystal fiber (PCF), resulting in improved techniques of pulse transformation leading to supercontinuum generation. A supercontinuum light source is subsequently used in conjunction with optical tweezers in a new technique of spectroscopic investigation. Some early results obtained using this technique are presented, as well as future directions.
