THIS communication reports the experimental observation of optical Raman scattering from oxygen and nitrogen in the atmosphere using a pulsed nitrogen ultraviolet laser 1,2 as a light source. Previous ...
Nanofabrication of electronic devices has reached a single nanometer scale (10-9 m). The rapid advancement of nanoscience and nanotechnology now requires atomic-scale optical spectroscopy in order to ...
Using a diamond crystal measuring just a few millimeters across in a carefully designed cavity, they tested a deliberately "noisy" input beam with linewidth exceeding 10 MHz. Their Raman scattering ...
Seeing chemistry unfold inside living cells is one of the biggest challenges of modern bioimaging. Raman microscopy offers a ...
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 ...
Detecting nanoscale plastic pollutants in the environment is a continuing challenge, and their presence is commonly only estimated rather than measured directly. A project at Vienna's TU Wien has now ...
Raman spectrography uses the Raman scattering of photons from a laser or other coherent light beam to measure the vibrational state of molecules. In chemistry, this is useful for identifying molecules ...
