Plastic pollution is a significant environmental issue, with microplastics (particles <5 mm) being particularly challenging to detect and quantify due to their small size. This study shows preliminary ...

Generation of 23-fs-long laser pulses with energy of 8.5 μJ at the wavelength of 1.8 μm is achieved by means of Raman conversion of 250-fs 50-μJ pulses at the wavelength of 1.03 μm. The Raman ...

Surface-enhanced Raman spectroscopy (SERS) is a powerful technique for vibrational spectroscopy, but analyzing mixtures in solution remains challenging due to spectral overlap. Integrating SERS with a ...
