Surface microcracks introduced during machining processes such as grinding, can reduce the glass's intrinsic strength by creating stress concentration points. These defects not only compromise the ...

Laser-driven 'mirrors' capable of reflecting or manipulating light have been produced. The 'mirrors' exist for only a fragment of time but could help to reduce the size of ultra-high power lasers, ...

Engineers at the University of California, Berkeley, have created mirrors that pack the same 99.9% reflectivity as current distributed Bragg reflector (DBR) mirrors, but do so in packages 20 times ...

There is a new type of EUV lithography using only four reflective mirrors overturns conventional technology and will contribute to advanced semiconductors at 7nm and below. Professor Tsumoru Shintake ...

The ‘mirrors’ exist for only a fragment of time but could help to reduce the size of ultra-high power lasers, which currently occupy buildings the size of aircraft hangars, to university basement ...
