Abstract

When external electric field is comparable to that of the typical interatomic fields (order of 10^9 V/cm), it is known as a 'strong-field'. Such strong fields can be experimentally achieved today by spatially focusing femtosecond lasers containing appropriate energy. The presence of atoms and molecules in such strong fields tend to primarily ionize through tunneling across the distorted Columb potential. While in the majority of the cases, the atoms or molecules are ionized and fragmented, in some cases, the ionized electron rescatters back into the ion core emitting high-order harmonics. In this talk, I will try to emphasize how we can use these two cases to measure tunneling dynamics and produce Extreme ultra-violet radiation for useful applications in spectroscopy and imaging.

Dr. Satya Sainadh Undurti actively works in the field of ultrafast laser-matter interaction and attosecond dynamics in strong laser fields. Dr. Undurti graduated with MS in physics from Indian Institute of Science in 2014. Later, he moved to Australia for pursuing doctoral studies at the Australian attosecond science facility, Griffith University, working towards measuring tunnelling time in atomic hydrogen. Later he joined as a post-doctoral research fellow at technion, where currently he performs high harmonic spectroscopy to probe chiral molecules and magnetic materials.

Prior to his PhD, he worked in RRI as a visiting student and research assistant in the field of quantum atom optics and cavity optomechanics. This formed a crucial part of his research pedigree that he still enjoys working in these fields, in his leisure time.
