We tackle one of the most common questions to arise when picking a Raman spectroscopy laser, “Should I choose a single, or multi-spatial mode laser for my application?”

Learn why the spectral properties, pulse width, and simpler design of picosecond lasers provide many advantages over femtosecond lasers for Raman spectroscopy.

Explore the uses of LIBS in the medical/biomedical application space by taking a look at some of the common applications as well as both laser and system requirements.

Learn about the fundamental optical design and advantages of a confocal Raman microscope, as well as the laser requirements and challenges inherent to this method.

This application note explains the concept of Raman Concatenation, which allows users to visualize the Raman spectra from 0 to 4000 cm by utilizing two lasers.

In general, many Raman measurements suffer from fluorescence, which forces the use of longer excitation wavelength (lower photon energy) lasers to prevent the fluorescence signal from overwhelming the Raman signal. However, this results in reduced sensitivity of low-cost silicon CCD detectors at higher wavenumbers, making it difficult (or impossible) to observe the “stretch” portion of the Raman spectra.
