Abstract

High-harmonic generation offers the possibility to generate table-top coherent radiation in the soft X-ray regime [1]. This enables high-resolution microscopy of biological and solid state samples. The high intensity required for HHG can be generated by amplifying pulses from a Ti:sapphire oscillator in an optical parametric chirped-pulse amplification (OPCPA) scheme, enabling the production of few-cycle pulses with terawatt peak powers [2]. To maximize the achievable flux of soft X-ray HHG, a high repetition rate pump system for OPCPA is required.
