Detecting the presence of nanoscale plastic particles in the environment has become a topic of concern for industrial societies worldwide, not least since particles of that size can evade the body's blood-brain barrier and damage metabolic processes.Optical technologies have been at the forefront of these monitoring efforts. Recent examples have included the use of stimulated Raman scattering to s...
Recently, the research team of the State Key Laboratory of High-Field Laser Physics at the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences has made progress in using high-field lasers to drive the even harmonic frequency shift of single-layer MoS2. The results were published in Optics Express under the title "Frequency shift of even-order high harmonic generation...
