New modeling approach helps laser glass design

Nd-doped phosphate glasses are used in high energy / high power laser applications due to their low nonlinear refractive index and high stimulated emission cross section. In order to ensure superior properties of laser glasses, ...

Where neutrinos come from

Russian astrophysicists have come close to determining the origin of high-energy neutrinos from space. The team compared data on the elusive particles gathered by the Antarctic neutrino observatory IceCube and on long electromagnetic ...
