The Fritz Haber Institute of the Max Planck Institute in Berlin has achieved a technological milestone. The infrared free electron laser operates in dual color mode for the first time. This globally unique technology makes it possible to conduct experiments on synchronous dual color laser pulses, opening up new possibilities for research.There are over a dozen free electron lasers worldwide, with ...
An interdisciplinary research group, including the German synchrotron radiation accelerator DESY and the Helmholtz Institute in Jena, Germany, reported that invisible gratings made of air not only are not damaged by lasers, but also maintain the original quality of the beam. The relevant research has been published in Nature Photonics under the title of "Acousto opt modulation of gigawatt scale la...
IntroductionIn recent years, inspired by insect compound eyes, artificial biomimetic compound eyes have shown great advantages in overcoming the limitations of existing imaging devices such as large, bulky, and heavy, and improving the performance of medical endoscopy, panoramic imaging, micro navigation, and robot vision due to their unique optical imaging solutions such as small size, distortion...
Researchers have developed a new experimental platform that can measure the light wave electric field captured between two mirrors with sub periodic accuracy. This electro-optical Fabry Perot resonant cavity will achieve precise control and observation of the interaction between light and matter, especially in the terahertz (THz) spectral range. The research results were published in the journal "...
