Reliable 5 fs and EUV Generation with a One-Box Titanium Sapphire Amplifier

Tracks of heavy ions 'imprinted' in lithium fluoride crystals. At the top, spot tracks observed under a fluorescence microscope in plates perpendicular to the heavy ion beam. At the bottom, the ion tracks in the parallel oriented plate (the blurring at both ends of the trace is an artifact of the depth of focus of the microscope). False colors.

Lithium fluoride fluorescent crystals track high-energy heavy ions such as iron

Single-layer OLED design could dramatically reduce display costs

When illuminated with laser light, a liquid-crystal elastomer robot (inset) about 1 cm long crawls up walls and across ceilings just like the banded snail sitting next to it.

Light-activated LC elastomer propels biomimetic “snail robot”

$Operation principles of a differential diffractive optical neural network. Since diffractive optical neural networks operate using coherent illumination, phase and/or amplitude channels of the input plane can be used to represent information.$
