Title: Michael Joseph Lefebvre: Innovator in Atomic Line Filters
Introduction
Michael Joseph Lefebvre is an accomplished inventor based in Del Mar, CA (US). He is known for his innovative contributions to the field of atomic line filters. His work addresses significant challenges in optical technology, particularly in the realm of resonant absorption lines.
Latest Patents
Lefebvre holds a patent for an invention titled "Excited State Atomic Line Filters." This invention provides a solution to the problem of the lack of ground state resonant lines at wavelengths significantly longer than those of visible light. The atomic line filters utilize alkali metal atomic vapor in a vapor cell, which is excited with a pump beam to an intermediate excited state. This process allows for the availability of a resonant absorption line at a desired wavelength. A magnetic field is applied to the cell, producing polarization rotation for polarized light at wavelengths near the resonant absorption lines. Consequently, all light is blocked by the cross polarizers, except for light near one of the spaced apart resonant lines. The polarization of light at certain wavelengths near the resonant is rotated in the cell, allowing it to pass through the output polarizer.
