US Patent Issued to Cornell University on Aug. 25 for "Third-harmonic frequency generator and generation method" (New York, Texas Inventors)

ALEXANDRIA, Va., Aug. 25 -- United States Patent no. 12,717,209, issued on Aug. 25, was assigned to Cornell University (Ithaca, N.Y.).

"Third-harmonic frequency generator and generation method" was invented by Jeffrey A. Moses (Ithaca, N.Y.), Noah Flemens (Ithaca, N.Y.) and Nuno Vinicius (Richardson, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "A third-harmonic generation method includes frequency-quadrupling a fundamental optical beam via cascaded second-harmonic generation to yield a fourth-harmonic optical beam. The method also includes down-converting the fourth-harmonic optical beam to yield a third-harmonic optical beam. A third harmonic generator includes a monolithic optical element having no...
