Creating Attosecond Pulses -- Made Simple
Electrons respond to light waves in much the same way that a ball would move on a child's oscillating teeter-totter. Here are three images illustrating how the ball would move if it were released from rest in the left image.
If the light is intense (of the teeter totter slope is large) the electron can move quite a large distance (in its world).
Attosecond pulses are created when intense light waves irradiate a gas of atoms or molecules. The light tugs the electron out of its orbit and then moves it like the marble on the teeter totter.
In the right image we see that the electron can collide with its parent ion when. During that collision it can emit a very short burst of light -- an attosecond pulse. The wavelength of the light can be almost as short as the wavelength of an X-ray.
Many atoms working together make the flash very bright.
