laserjäähdytystekniikoita
Laserjäähdytys, known in English as laser cooling, is a technique used to reduce the temperature of atoms or ions to extremely low levels, often approaching absolute zero. This is achieved by using lasers to slow down the motion of these particles. The fundamental principle relies on the Doppler effect. When a laser beam is tuned to a frequency slightly lower than an atom's resonant frequency, atoms moving towards the laser will perceive the light as being at their resonant frequency due to the Doppler shift. This causes them to absorb a photon.
When an atom absorbs a photon, it gains momentum from the laser beam, which is directed opposite
By using multiple laser beams from different directions, a six-beam configuration called a "magical trap" or
