Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...
A well-established technique in industry, laser micromachining uses lasers to mark, cut, and drill workpieces with extremely high precision. 1 Using ultrashort pulsed lasers, laser-based solutions are ...
In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative term – the metal is ...
