Forcibly driven coherent soft phonons in GeTe with intense THz-rate pump fields
coherent soft phonons GeTe intense THz-rate pump fields
2010/11/23
We propose an experimental technique to generate large amplitude coherent phonons with irradiation of THz-rate pump pulses and to study the dynamics of phase transition in GeTe ferroelectrics.When a s...
Spectral dependence of purely-Kerr driven filamentation in air and argon
Spectral dependence purely-Kerr driven filamentation argon
2010/11/16
Based on numerical simulations, we show that higher-order nonlinear indices (up to $n_8$ and $n_{10}$, respectively) of air and argon have a dominant contribution to both focusing and defocusing in t...
