Pushing periodic disorder induced phase-matching into deep-ultraviolet spectral region

Phase matching condition is the key criteria for efficient nonlinear frequency conversion. Here, Scientists in China employed an additional periodic phase (APP) technique to meet the phase-matching condition in quartz crystal and experimentally demonstrated the efficient nonlinear frequency conversion from the visible to the deep-ultraviolet spectral region. The APP theory and generated visible to deep-ultraviolet radiation would revolutionize next-generation nonlinear photonics and their further applications.
