A research team has successfully developed a self-locked Raman-electro-optic (REO) microcomb on a single lithium niobate chip. By synergistically harnessing the electro-optic (EO), Kerr, and Raman ...

A new optical phenomenon has been demonstrated by an international team of scientists led by physicists at the University of Bath, with significant potential impact on pharmaceutical science, security ...

Raman spectroscopy is a highly efficient technique used to identify chemicals. While the Raman Effect has been known for almost 100 years, recent developments have enabled Raman spectrometers to be ...

The year is 1928. Inside a darkened laboratory at the Indian Association for the Cultivation of Science in Kolkata, a man is crouched over bottles of liquid, one by one, in near-total darkness. He has ...

Raman spectroscopy, compatible with molecular and material samples, is one of the most popular quantitative and qualitative spectroscopic techniques. A sample has a distinct Raman “fingerprint” that ...

A team led by Prof. DONG Chunhua from the University of Science and Technology of China (USTC), in collaboration with Prof. BO Fang's group from Nankai University, has successfully developed a ...

Raman spectroscopy has been highlighted as a vital tool for characterizing 2D materials-based van der Waal heterostructures. In this article, we explore its applications in analyzing graphene, TMDs ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...
