Figure | Focused terahertz pulse ionizing a solid target.

Caption

(a) A series of 15-THz beam profiles captured at various positions along the propagation when focused by a concave metallic mirror. The spot size is as small as 43 micrometers in a full width at half maximum at the focus. (b) Plasma florescence emitted from a solid target, irradiated by an intense terahertz pulse, and captured by a camera. (c) Microscope image of a semiconductor surface damaged by an ionizing terahertz pulse.
