Electron shelving induced lasing in cold bosonic atoms in optical lattice

TL;DR

This paper explores how electron shelving in cold bosonic helium atoms within an optical lattice can induce lasing, with control over stimulated emission via magnetic fields, highlighting potential for novel laser mechanisms.

Contribution

It demonstrates the possibility of lasing in cold helium atoms in an optical lattice through electron shelving and magnetic field control, a novel approach in atomic physics.

Findings

Lasing can be achieved at specific points in the optical lattice.

Magnetic fields enable coherent control of stimulated emission.

Electron shelving facilitates metastable states for lasing.

Abstract

We calculate the absorption spectrum of cold three level Helium atoms in lambda configuration in an optical lattice.Our results show the possibilty of lasing at certain points on the optical lattice which are capable of rendering one of the transitions metastable as compared to the other. A coherent control over the stimulated emission is possible using an axial magnetic field.
