Our Experience with RGB Laser Systems in Raman Applications

In our ongoing efforts to elevate the precision and quality of Raman measurements within
our laboratory, we undertook a comprehensive evaluation of various laser units from the
market. This rigorous testing phase allowed us to carefully assess the performance,
reliability, and technical specifications of each system. Following a thorough comparison of
the results, the laser from RGB Laser Systems consistently distinguished itself. Its
exceptional performance, particularly in meeting our stringent technical requirements, made
it the clear choice for our continued work and a significant upgrade to our existing setup.

RGB Laser Systems is a manufacturer of continuous-wave lasers and also develops
laser sources specifically designed for Raman spectroscopy, with a focus on achieving a
very narrow spectral linewidth, essential for high-resolution Raman measurements. Their
systems also offer several practical advantages, such as an ultra-compact design—ideal
for integration into space-constrained setups—and custom configuration options,
including a broad range of wavelengths, output powers, and interfaces.

We tested the lasers on a range of mineralogical samples, where strong fluorescence and
low Raman signal intensity often present significant challenges. Compared to other lasers,
the RGB laser provided cleaner spectra and better signal stability, especially on
problematic samples.

The laser was easy to integrate into our existing setup and has operated reliably throughout
our measurements. This performance makes the RGB laser a practical, effective, and
highly recommended solution for our mineral analysis and research in general.
