Deep-ultraviolet resonance Raman spectroscopy for chemical sensing

摘要

Resonance Raman spectroscopy is an emerging spectroscopy tool capable of highly specific and highly sensitive analysis of biological molecules in solutions. The complexity of experimental set-up and reliance on laser sources with very short life-time and very high maintenance requirement were always considered the major bottle-neck problem on the way of wide spread of applications of deep-UV Raman spectroscopy in biology and medicine. In this report, we present the design of a very inexpensive system based on a diode-pumped solid-state laser system capable of performing Raman analysis in the deep UV.
