Contribution

It develops a new Schrödinger equation approach to describe laser cooling, providing theoretical predictions consistent with experiments and proposing a new proportionality relation.

Findings

Atoms can be cooled using the new quantum theory.

The cooling temperature is proportional to vibrational frequency.

The predicted temperature formula matches experimental results.

Abstract

In this paper, we study the laser cooling mechanisms with a new quantum theory approach by applying a new Schrodinger equation, which can describe a particle in conservative and non-conservative force field. With the new theory, we prove the atom in laser field can be cooled, and give the atom cooling temperature, which is accordance with experiment result. Otherwise, we give new prediction that the atom cooling temperature is directly proportional to the atom vibration frequency. By calculation, we find they are: $T=0.4334\omega$.
