Laser-induced ionization in matter—gas, cluster, liquid, and solid—occurs when a laser pulse with sufficient intensity is focused into a target material, creating electrons and ions through nonlinear processes of laser-matter interaction. Photoionization is an effective way to generate transient currents and electromagnetic radiation covering the spectrum from microwaves to X-rays.
