Soft X-ray continua generation via HHG with sub-cycle synthesized laser fields

Abstract

Isolated attosecond soft X-ray continua are presented as generated with a synthesized infrared laser field. Sub-cycle non-sinusoidal electric fields supersede the need for any gating techniques. A vast scan of multiple synthesis parameters is presented and the interplay of waveform dependent macroscopic effects for synthesized sub-cycle driving pulse are discussed.
