In situ measurement and reconstruction in three dimensions of femtosecond inscription-induced complex permittivity modification in glass.
We demonstrate a new approach to in situ measurement of femtosecond-laser-pulse-induced changes in glass, enabling the three-dimensional reconstruction of the induced complex permittivity modification. The technique can be used to provide single-shot and time-resolved quantitative measurements with a micrometer-scale spatial resolution.
