Multiphoton lithography (MPL) is a technique that uses ultra-short laser pulses to create complex three-dimensional (3D) structures at the micro- and nanoscale. It is based on the principle of multiphoton absorption (MPA), ...
A new way of producing coherent light in the ultra-violet spectral region, which points the way to developing brilliant table-top X-ray sources, has been produced in research led at the University of Strathclyde.
