Abstract

High peak power laser systems are capable of delivering 266 and 213-nm light pulses for proximal detection using Raman spectroscopy. These lasers are becoming more energy efficient and compact making them ideal as deep-UV excitation sources in hand-held devices. This talk will describe our efforts to over come some of the difficulties associated with using UV-Raman spectroscopy in a compact, battery operated system with a unique optical design with gated detection allowing spectra to be collected in daylight conditions from distances of 20 meters and more.
