Title: Timothy J. Madden: Inventor in Gas-Phase Iodine Laser Technology.

Introduction

Timothy J. Madden is an inventor associated with Albuquerque, New Mexico. His patent work includes gas-phase iodine laser technology developed for the United States of America as Represented by the Secretary of the Air Force. Madden is credited with 2 patents.

Latest Patents

Madden’s listed patents focus on continuous-wave, all-gas-phase iodine lasers operating at 1.315 microns. These systems use energy transfer between metastable nitrogen chloride and ground-state iodine atoms to produce laser emission.

“Supersonic All Gas-Phase Iodine Laser” describes a transverse-flow device in which gases pass from a subsonic combustor through a converging-diverging supersonic slit nozzle and into a downstream supersonic section. An optical resonator intersects the flow. The patent describes transforming chemical reagents in the subsonic and supersonic sections to support laser operation.

“Continuous Wave All Gas Phase Iodine Laser (AGIL)” describes a laser based on the energy-transfer reaction between metastable nitrogen chloride and ground-state iodine atoms. The patent highlights potential advantages over aqueous-based chemical oxygen iodine lasers, including reduced weight, operation in zero gravity, and heat rejection through the exhaust.

Career Highlights

Madden’s patent portfolio reflects work on chemical laser systems and gas-flow designs. The inventions address ways to generate continuous-wave laser output using gas-phase reactions and supersonic flow.

Collaborations

The listed coworkers associated with Madden include Gordon D. Hager and Christopher B. Cooper. His patents were assigned to the United States of America as Represented by the Secretary of the Air Force.
