Questions:
1. Attosecond physics deals with light pulses that are emitted for a few attoseconds at a time, no more. By bouncing such pulses off of electrons, scientists practically have a camera that can ‘see’ electrons changing their properties. How much of a second is one attosecond?
2. Modern attosecond physics is partly rooted in innovations to build powerful lasers. One such innovation was recognised by the 2018 Nobel Prize for physics – awarded to Arthur Ashkin, Gérard Mourou and Donna Strickland. Of them, Dr. Mourou and Dr. Strickland were awarded for being the first to practically implement _______ _____ _____________. Fill in the blanks.
