Can I get an ELI5 of this principle? I read the Doppler cooling part but I can't connect the dots.
Heat energy is the amount of particle wiggling.
With precisely tuned and oriented lasers you can clamp a particle in space, thus prevent it from wiggling.
No wiggling -> very cold.
It's like slowing cars by crashing another car into them. But it's photons instead from the exact opposite direction.
Allow me to introduce you to this
