Laser Spectroscopy
Laser spectroscopy investigates how light interacts with matter to reveal chemical composition, molecular structure, and physical properties. The combination of tunable laser sources and advanced spectroscopic techniques enables highly selective and sensitive measurements across a broad spectral range. Applications span from Raman and vibrational spectroscopy to ultrafast, time-resolved, and high-resolution studies of materials, molecules, and dynamic processes.
Raman Spectroscopy
Raman spectroscopy reveals the vibrational fingerprint of molecules by analyzing the light scattered from a sample. This powerful technique enables non-destructive chemical identification and characterization of materials across chemistry, biology, and materials science. Tunable lasers are particularly valuable for advanced Raman methods such as SRS and CARS, enhancing sensitivity and molecular selectivity.
Pump-Probe and Time-Resolved Spectroscopy
Capturing how materials and molecules evolve after excitation provides unique insight into ultrafast physical, chemical, and biological processes. By following transient states, energy transfer pathways, charge carrier dynamics, and relaxation mechanisms on femtosecond timescales, researchers can uncover fundamental behavior that remains hidden in steady-state measurements. Ultrafast and tunable laser sources enable selective excitation and probing across diverse materials and spectral regions.
Vibrational Spectroscopy
Molecular vibrations provide a unique fingerprint that reveals the composition and structure of matter. By probing these characteristic vibrational modes, researchers can identify molecules, study chemical bonds, and monitor reactions with high specificity. Tunable laser sources in the IR enable selective access to vibrational transitions, supporting applications in chemistry, materials science, environmental analysis, and life sciences.
Non-linear Spectroscopy
When light interacts with matter at high intensities, new optical phenomena emerge that reveal information beyond the reach of conventional measurements. By probing nonlinear light-matter interactions, researchers can investigate molecular structure, material properties, and interfacial dynamics with exceptional sensitivity. These powerful techniques provide unique insight into complex systems, enabling advanced studies in chemistry, materials science, and surface physics.
Fluorescence Spectroscopy
Fluorescence spectroscopy harnesses the light emitted by molecules and materials following optical excitation, providing highly sensitive insight into their composition, structure, and environment. Widely used in chemistry, biology, and materials science, it enables the detection of subtle changes and trace species. Tunable laser sources maximize excitation efficiency and measurement sensitivity across diverse applications.
High Resolution Spectroscopy
High-resolution spectroscopy enables the precise measurement of atomic and molecular transitions, revealing subtle spectral features that are inaccessible with conventional techniques. CW narrow-linewidth laser sources are essential for these applications, providing exceptional frequency stability, spectral purity, and accuracy for precision metrology, fundamental physics, quantum technologies, and advanced molecular characterization.

“
Radiantis were very flexible with our requirements and perfectly matched to our technical needs and budget. Radiantis OPO has enabled us to carry out advanced optical characterisation of our systems across the UV, Visible and IR, and has proven to be a very reliable and easy-to-use system, delivering high and stable power and fast automated tuning across the complete spectral range. Radiantis team were very friendly and provided a professional and comprehensive user training to key researchers in my lab, which enabled us to operate the OPO successfully and reliably over many years.
”
“
The wide tuning range of our Radiantis OPO system has allowed us to access wavelength regimes that have enabled a number of nonlinear optics experiments that would otherwise not have been possible. Radiantis have been very responsive and any problems have always been dealt with swiftly, with engineers being sent over to our lab for extended visits whenever required.
