Ultra-short laser pulses may affect bandgap material in a way of changing material optical, electronic, and magnetic properties. Result of ultra-short pulse and band gap material interaction is a combination of multiple well known physical effects that occur when photons at very high rate changing material properties for a short time. Combinations of such effects can be described as Ultrafast Bandgap Photonics phenomena. Key stone of Ultrafast Bandgap Photonics is in time difference between excitation and relaxation processes in bandgap material. Time difference allows to use Ultrafast Bandgap Photonics in applications ranging from low observables to optically induced ambient temperature superconductivity.
