Attosecond angular streaking and tunnelling time in atomic hydrogen
U. Satya Sainadh, Han Xu, Xiaoshan Wang +9
Tunnelling, one of the key features of quantum mechanics, ignited an ongoing debate about the value, meaning and interpretation of 'tunnelling time'. Until recently the debate was…

Precise and accurate measurements of strong-field photoionisation and a transferrable laser intensity calibration standard
W. C. Wallace, O. Ghafur, C. Khurmi +12
Ionization of atoms and molecules in strong laser fields is a fundamental process in many fields of research, especially in the emerging field of attosecond science. So far, demons…

Measuring laser carrier-envelope phase effects in the noble gases with an atomic hydrogen calibration standard
Champak Khurmi, W. C. Wallace, Satya Sainadh U +6
We present accurate measurements of carrier-envelope phase effects on ionisation of the noble gases with few-cycle laser pulses. The experimental apparatus is calibrated by using a…
