abstract
Deep-UV Raman spectroscopy is a powerful way to collect chemically specific information about complex samples. The availability of inexpensive and reliable light sources in the spectral region below 250 nm has been always considered a major bottleneck problem on the way of a widespread of this powerful spectroscopic technique. We report on the efficient fourth-harmonic generation of a low-power microchip Nd:YAG laser operating at 946 nm. High-quality deep-UV Raman spectra were collected using a newly developed laser source. Copyright 2013 John Wiley & Sons, Ltd.
