Grating-like nanostructures formed by the focused fs laser pulse in the volume of transparent dielectric

The evolution of optical discharge induced in the volume of transparent dielectric by a focused fs laser pulse is studied under condition of ionization instability that results in deep small-scale periodic modulation of breakdown plasma parameters in the direction of laser polarization. Laser pulse ...
