High-energy few-cycle pulses: post-compression techniques
Advances in Physics: X, 2021 Contemporary ultrafast science requires reliable sources of high-energy few-cycle light pulses. Currently two methods are capable of generating such pulses: post compression of short laser pulses and optical parametric chirped-pulse amplification (OPCPA).
