Excellent nonlinear optical materials simultaneously meet the requirements of large SHG response, phase‐matching capability, wide transparency windows, considerable energy band‐gap, good thermal stabi...
Self-phase modulation of a single-cycle terahertz pulse by nonlinear free-carrier response in a semiconductor
Self-phase modulation single-cycle terahertz pulse nonlinear free-carrier response semiconductor
