Optoelectronic measurements of light fields by sub-cycle carrier injection in dielectrics (Conference Presentation)

We present a new technique to measure electric fields over a 1 PHz bandwidth spanning the infrared to ultraviolet with sub-femtosecond temporal resolution via the sub-cycle control of injected charge carriers in dielectric media. The fidelity of the reconstructed electric fields are benchmarked against attosecond streaking and electro-optic sampling and provide detailed information about the temporal evolution of the charge carrier density in materials exposed to strong laser fields. The resulting optoelectronic technique allows for many methods of attosecond physics to be applied to a compact, table-top measurement, without necessitating the generation of attosecond XUV pulses.
