Non-linear propagation effects of intense femtosecond pulses on below bandgap harmonics in solids
Non-linear propagation effects of intense femtosecond pulses on below bandgap harmonics in solids
The non-linear propagation of the intense near-infrared (NIR) driving field in crystals poses a challenge and can offer an opportunity to control the spectral properties of harmonics in solids. Here, we have investigated the non-linear propagation effects in wide bandgap dielectrics such as Magnesium Oxide (MgO), Chromium (Cr) doped MgO …
