The transmission of electromagnetic waves (such as lasers) in plasma is a fundamental issue in plasma physics. In general, electromagnetic waves cannot be transmitted in high-density plasma, but their transmission and energy transfer play a crucial role in applications such as fast ignition laser fusion, laser particle acceleration, and ultra short and ultra bright radiation sources.In 1996, S. fr...
Researchers from the University of Aveiro in Portugal and the School of Engineering at Porto Institute of Technology (ISEP) in Portugal reported a study on the influence of laser beam intensity distribution on the geometric shape and process stability of lock holes under green laser radiation. The relevant paper titled "Influence of Laser Beam Intensity Distribution on Keyhole Geometry and Process...
A novel method is used to deflect the laser beam using only air. The interdisciplinary research team reported in the journal Nature Photonics that invisible gratings made solely of air not only do not suffer damage from lasers, but also retain the original quality of the beam. The researchers have applied for a patent for their method.Technology and PrinciplesThis innovative technology utilizes so...
