Title: The Innovative Contributions of Denise M. Krol
Introduction
Denise M. Krol is a prominent inventor based in Murray Hill, NJ (US). She has made significant contributions to the field of optical technologies, holding a total of 2 patents. Her work focuses on enhancing the efficiency of optical second harmonic generation, which has important applications in various technological domains.
Latest Patents
Denise's latest patents include the "Resonantly Enhanced Optical Second Harmonic Generator." In this invention, she and her team discovered that the conversion efficiency of doped glass optical second harmonic generators can be significantly enhanced when the frequency of the fundamental beam or the harmonic beam is tuned near the resonance frequency of an optical transition in the dopant. This resonant enhancement was demonstrated for Tm doped aluminosilicate glass fibers, where tuning the fundamental writing beam to a resonance frequency increased the second harmonic output by a factor of 10³.
Another notable patent is the "Optical Frequency Second Harmonic Generator." In this invention, Denise and her colleagues discovered photo-induced second harmonic generation in rare earth doped glass bodies that are free of germanium. They found that multivalent rare-earth doped glass bodies can achieve a conversion efficiency of second harmonic generation exceeding 10⁻³ % per watt, surpassing the reproducible efficiency of germanium doped glass. This invention includes a light source of a desired frequency, comprising a body of glass doped with a multivalent rare earth element, an optical input source of light at one-half the desired frequency, and utilization means for receiving light passing through the body.
