Intense ultrashort light pulses interacting inside dielectrics can create nanoplasmas due to localized inhomogeneous nonlinear ionization. These nanoplasmas are bound inside the dielectric and are transient as their density changes during the light pulse-from underdense to quasi-metallic plasma densities. Interaction of light at the transient plasma-dielectric interface can lead to local field enhancements, similar to that observed in the metal-dielectric interface, which control the growth of nanoplasmas. We discuss the differences in the interaction of light at these two interfaces and demonstrate that transient nanoplasmonics can imprint periodic nanostructures inside the dielectric.
