The Kerr Response Is Measured in the Field
Field-resolved pump-probe spectroscopy separated germanium's instantaneous nonlinear phase shift from delayed carrier effects at five micrometers.
Summary
Field-resolved pump-probe spectroscopy separated germanium's instantaneous nonlinear phase shift from delayed carrier effects at five micrometers.
The measured phase followed the pump envelope and vanished when the pulses no longer overlapped. Its linear intensity scaling yielded a nonlinear refractive index of 0.87 plus or minus 0.16 times 10^-17 square meters per watt.
Why it matters
Field-resolved pump-probe spectroscopy separated germanium's instantaneous nonlinear phase shift from delayed carrier effects at five micrometers.
Limits and context
No additional limitation was separately recorded.
