Abstract

This work presents a novel approach for nonlinear pulse compression in a multipass
cell for an extreme ultraviolet frequency comb which will be employed for quantum
logic spectroscopy of highly charged ions. The nonlinear crystal used is potassium
pyrophosphate (KDP) which exhibits anomalous dispersion around the central wavelength
1030nm of the seed laser. This enables tuning of the dispersion by adjusting the
pressure of a normal dispersive gas which fills the multipass cell. Chirped mirrors are
thus not necessary and pulse compression becomes flexible by adjusting the number of
passes in the cell. This proposal is supported by numerical simulations.
For analysis of the pulse compression, a pulse characterization system for intensitybased
and interferometric autocorrelation and frequency-resolved optical gating is set
up.
