A research team in Japan has designed a flexible and shapable X-ray reflector, achieving significant accuracy and higher stability at the atomic level.This new technology, developed by Satoshi Matsuyama and Takato Inoue from the Graduate School of Engineering at Nagoya University, in collaboration with the Japanese Institute of Physical and Chemical Research and JTEC Corporation, improves the perf...
German researchers have developed a method for controlling and manipulating optical signals by embedding liquid crystal layers into waveguides created by direct laser writing. This work has produced devices capable of electro-optic control of polarization, which may open up possibilities for chip based devices and complex photonic circuits based on femtosecond write waveguides.Researcher Alexandro...
Recently, according to Tom's Hardware, Lawrence Livermore National Laboratory (LLNL) in the United States is developing a PW (1015 W) level large aperture thulium (BAT) laser. It is reported that this laser has the ability to increase the efficiency of extreme ultraviolet lithography (EUV) light sources by about 10 times, and may potentially replace the carbon dioxide laser used in current EUV too...
For example, the commonly used square shell battery cells for power batteries include laser welding of cover explosion-proof valves, laser welding of pole columns, and laser welding of cover plates and shells. During the process of laser welding of aluminum alloy, it is easy to generate unqualified phenomena such as explosion points, pores, welding cracks, excessive depth and width of fusion. ...
Recently, the team from the State Key Laboratory of Intense Field Laser Physics, Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences found that the third-order harmonics induced by air filamentation of high repetition rate femtosecond lasers have significant self jitter. To solve this bottleneck problem, a solution based on an external DC electric field was proposed, which sign...
