LASER PHYSICS:
Powerful Pulses Color Thomson Scattering

Alexander Hellemans

Not long after identifying the electron in 1897, British physicist J. J. Thomson showed that powerful pulses of light could make electrons oscillate up and down and reemit light at the same frequency in all directions, a phenomenon later dubbed Thomson scattering. Now, almost 100 years later, researchers have applied much stronger light to electrons and coaxed them into performing a more complex dance step, tracing out figure-8 shapes and reemitting the light in rainbow colors.
