Stimulated Raman scattering (SRS) microscopy is an optical vibrational spectroscopic imaging technique and has emerged as an appealing label-free imaging tool for tissue and cell imaging and ...

For anisotropic crystals, it has been known for many years that the birefringence effect rising from anisotropic refractive index should be considered for angle-resolved polarized Raman (ARPR) ...

The Raman effect is based on light scattering. In most instances, light that “hits” a molecule does not interact with it and so the photon does not lose energy. This process is known as elastic ...

Visualization of glucose molecule "fingerprint information". (a) SNOM-TERS platform based on fiber vector light field; Background-free tip nanofocusing light source (b) and its electric field ...

Ultraintense X-ray free-electron laser pulses of attosecond duration can enable new nonlinear X-ray spectroscopic techniques to observe coherent electronic motion. The simplest nonlinear X-ray ...

Spatially masked optical Kerr effect (SM-OKE) spectroscopy is a nonresonant femtosecond pump–probe technique capable of measuring isotropic contributions to the transient birefringence of molecular ...

Raman Scattering in fiber is a nonlinear process that converts some of the photons at fiber laser wavelength to photons at relatively longer wavelength. The higher the laser power the stronger the ...

In 1986, under Prime Minister Rajiv Gandhi’s leadership, the Indian government declared February 28 as National Science Day ...
