Optical phase conjugation in backward Raman amplification
Qing Jia, Kenan Qu, Nathaniel J. Fisch
Compression of an intense laser pulse using backward Raman amplification (BRA) in plasma, followed by vacuum focusing to a small spot size, can produce unprecedented ultrarelativis…

Theory of electromagnetic wave frequency upconversion in dynamic media
Kenan Qu, Qing Jia, Matthew R. Edwards +1
Frequency upconversion of an electromagnetic wave can occur in ionized plasma with decreasing electric permittivity and in split-ring resonator-structure metamaterials with decreas…

Plasma q-plate for generation and manipulation of intense optical vortices
Kenan Qu, Qing Jia, Nathaniel J. Fisch
An optical vortex is a light wave with a twisting wavefront around its propagation axis and null intensity in the beam center. Its unique spatial structure of field lends itself to…
