Title: James J. Childs and the Microlaser Patent.

Introduction

James J. Childs is an inventor associated with Reading, Massachusetts, and the Massachusetts Institute of Technology. His patent work includes an invention titled “Microlaser,” which describes a single-atom laser based on a high-finesse optical cavity.

Latest Patents

The available information identifies one patent for Childs: “Microlaser.” The invention uses two opposed reflectors to form a high-Q optical cavity and introduces individually excited atoms into it. As each atom enters, it can emit a photon at a frequency matched to the cavity’s resonance. The cavity sustains the photons long enough to interact with subsequent atoms, enabling the emission of coherent light in the optical frequency spectrum. Childs is credited with 1 patent.

Career Highlights

Childs’s listed affiliation is the Massachusetts Institute of Technology. The Microlaser patent describes a design in which the average number of photons in the cavity exceeds one while the average number of atoms remains below one, a distinctive operating principle for a single-atom microlaser.

Collaborations

The listed coworkers associated with Childs include Ramachandra Rao Dasari and Michael S. Feld.

Conclusion

James J. Childs’s recorded patent contribution is the Microlaser, an invention that uses interactions between individual atoms and a high-Q optical cavity to produce coherent light.
