Latest Patents

Margaret Mumane's latest patents include groundbreaking advancements in high-order harmonic generation. The first patent, titled "High-order harmonic generation in a capillary discharge," describes a pre-ionized medium created by a capillary discharge that results in more efficient use of laser energy. This innovation extends the cutoff photon energy and reduces the distortion of the laser pulse as it propagates down the waveguide. The enhancements observed stem from a combination of reduced ionization energy loss and reduced ionization-induced defocusing of the driving laser, along with waveguiding of the driving laser pulse. Additionally, the discharge plasma provides a means to spectrally tune the harmonics by tailoring the initial level of ionization of the medium.

The second patent, "Phase matching of high order harmonic generation using dynamic phase modulation caused by a non-collinear modulation pulse," focuses on phase matching high harmonic generation. This process utilizes a single, long-duration non-collinear modulating pulse that intersects the driving pulse. A femtosecond driving pulse is focused into an HHG medium, such as a noble gas, to facilitate high-harmonic generation, particularly in the X-ray region of the spectrum. The non-collinear pulse modulates the field experienced by the electrons while they are separated from their atoms, improving HHG phase matching by increasing constructive interference areas relative to destructive interference areas.
