Researchers at the University of St. Andrews in Scotland have manufactured the first organic semiconductor laser to operate without the need for a separate light source - which has proven to be extremely challenging. The new all electric driven laser is more compact than previous devices and operates in the visible light region of the electromagnetic spectrum. Therefore, its developers stated that...
It is reported that researchers from the University of Salamanca in Spain have demonstrated a high-order harmonic spectroscopy scheme generated by the interaction between a structured driving beam and a crystal solid target. This work promotes the topological analysis of high-order harmonic fields as a spectroscopic tool to reveal nonlinearity in the coupling of light and target symmetry. The rele...
Recently, the research team of the Special Glass and Fiber Research Center of the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, aimed at the demand for in-situ detection of Raman signals, expanded the functions of the laboratory commercial Renishaw Invia confocal micro Raman spectrometer by usi...
Laser is considered a sharp sword that cuts iron like mud, but even sharper swords can have tricky moments. For example, in certain scenarios, there are materials with higher reflectivity, such as silver, copper, etc., known as "high reflection materials". High reflective materials have a low absorption rate for lasers, making them difficult to process and potentially causing equipment failure or ...
A new study conducted by the US Department of Energy's SLAC National Accelerator Laboratory has revealed the strange behavior of gold when impacted by high-energy laser pulses.When certain materials are subjected to strong laser excitation, they will quickly disintegrate. But gold is exactly the opposite: it becomes more resilient and resilient. This is because the way gold atoms vibrate together ...
