Deep UV Raman spectroscopy is an exquisite tool for chemical sensing and imaging, which provides superior sensitivity and specificity, while allowing Raman measurements to be performed in a bright room with no residual fluorescence background, which can potentially corrupt the useful signal. However, the lack of appropriate laser sources limits the field of applications and penetration of this advanced spectroscopic technique.
In this report, I will present our outgoing efforts to develop versatile laser sources in the wavelength range from 200 to 260 nm for fast and reliable deep UV Raman spectroscopy. I will provide with the outline of three different configurations we have developed and will illustrate the power of deep UV Raman spectroscopy with several practical examples.
