Abstract

By two-photon resonant three-photon ionization in atomic potassium, the ion current decay curve was measured. From the relation between ion current and multi-photon dynamic parameter, photo-ionization cross-section of 6S state in atomic potassium was determined. When excited with one-photon at 766.4 nm and 769.8 nm, the atomic potassium was ionized by energy pooling effect.
