SUMMARY
The relationship between reabsorption and heating in laser cooling is critical to understanding the Doppler limit on temperature. As discussed, spontaneous emission is essential for laser cooling, but the reabsorption of emitted photons by other atoms leads to increased kinetic energy, resulting in heating. This phenomenon is particularly pronounced in dense atomic systems, where the likelihood of reabsorption rises, causing equilibrium temperatures to increase. Key references include Phillips' paper on laser cooling and the study on optical lattices.
