Title: John J Donoghue: Innovator in Optical Phase Conjugation
Introduction
John J Donoghue is a notable inventor based in South Boston, MA (US). He has made significant contributions to the field of optical engineering, particularly through his innovative patent related to self-pumped optical phase conjugation.
Latest Patents
Donoghue holds a patent for "Self-pumped optical phase conjugation with a sodium Raman laser." This invention involves a three-level atomic system in a resonance Raman configuration, where self-pumped optical phase conjugation is achieved using self-induced standing waves in a Raman laser. The patent demonstrates that self-pumped reflectivities approaching five percent can be obtained for input intensities of 20 watts per square cm. This low optical input intensity, combined with predicted submicrosecond response times, suggests that the resonant Raman interaction may lead to a new class of promising non-linear optical materials.
