Title: The Innovative Contributions of Khanh Kieu
Introduction
Khanh Kieu is a prominent inventor based in Tucson, AZ (US), known for his significant contributions to the field of laser technology. With a total of 12 patents, Kieu has made remarkable advancements that enhance the efficiency and capabilities of laser systems.
Latest Patents
Among his latest patents is a groundbreaking invention titled "Laser generation apparatus and sources using the same." This invention allows for the efficient generation of harmonic frequencies from broadband sources. The technology involves over-compression and under-compression of a split signal, resulting in two beams chirped in opposite directions. These beams can be combined in a non-linear crystal to generate a narrow-band harmonic signal from a broadband source. Another notable patent is "All-fiber single-cavity dual-comb for coherent anti-stokes Raman scattering spectroscopy based on spectral focusing." This method involves generating first and second optical pulse trains with different and adjustable repetition rates. One pulse train is directed in a continuous wave (CW) direction while the other is directed in a counter-clockwise (CCW) direction. The process includes applying frequency shifts and linear chirps to the optical pulses, which are then combined to define a combined beam for use in a CARS spectroscopic system.
