    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.
