under a full quantum description, the HHG process emits light with quantum features. However, experimental validation of such predictions remained elusive until, recently, a team led by the ...

But the electron's quantum wavefunction also diffuses ... patterned nonlinear crystals have been demonstrated for HHG by colliding light from the drive laser with a (relatively weak) laser beam ...

An international team of engineers and physicists have found a way to use quantum light to improve the performance of cutting-edge spectroscopy. Their new technique enables measurements of ...

The proposed nanowire structure consists of a GaAs tip with a tip angle as small as 4° and a quantum ... HHG sources. When a laser beam passes through a nonlinear optical material, it generates ...
