Observing the Surface-Enhanced Signal of Water in an Aqueous Dispersion
Researchers from the Polish Academy of Sciences, Lodz University of Technology, and the University of Warsaw use a PHAROS laser from Light Conversion to observe the surface-enhanced (SE) signal of water in an aqueous dispersion of silver nanoparticles. The observation techniques used were spontaneous Surface-Enhanced Raman Spectroscopy (SERS) and Surface-Enhanced Femtosecond Stimulated Raman Spectroscopy (SE-FSRS) processes. This work opens up exciting perspectives for studies of the vibrational relaxations and dynamics of water molecules.
PHAROS is a femtosecond laser system combining millijoule pulse energies and high average powers. PHAROS features a mechanical and optical design optimized for industrial applications such as precise material processing. Compact size, an integrated thermal stabilization system, and sealed design allow PHAROS integration into machining workstations.
