Observation of ultrafast impact ionization in diamond driven by mid-infrared femtosecond pulses

We report on the observation of ultrafast impact ionization in monocrystalline diamond driven by high-intensity mid-infrared femtosecond laser pulses. The measurements are based on monitoring the excited carrier population during and after the interaction of the pre-excited sample with a strong infr...
