Abstract
We use the confluence of two intensity-dependent processes - low-order harmonic generation and self-phase modulation - to spatio-temporally couple and compress few-cycle pulses to be sub-cycle in duration. These half-cycle transient fields self-focus in space and in time (increasing the peak field strength) and can generate isolated attosecond pulses. We explore some of the parameter spaces available to create these half-cycle transients and methods of improving the half-cycle contrast. We also discuss how these pulses can increase high harmonic generation efficiency in the water window.
