Extreme Ultraviolet Polarimetry with Laser-Generated High-Order Harmonics
… (EUV) polarimeter, which employs laser-generated high-order harmonics as the light source. This relatively high-flux directional EUV source has available wavelengths between 8 nm and 62 nm and easily rotatable linear polarization. The polarimeter will aid researchers at BYU in characterizing EUV …

Phase-Matching Optimization of Laser High-Order Harmonics Generated in a Gas Cell
… nm bandwidth) laser pulses are used to study high-order harmonic generation in helium- and neon-filled gas cells of various lengths. Harmonic orders in the range of 50 to 100 are investigated. A semi-infinite cell geometry produces brighter harmonics than cells of sub-centimeter length. In the …

Probabilistic assessment of the impact of integrating large-scale high-power fast charging stations on the power quality in the electric power distribution systems
… assesses the impacts of integrating large-scale high-power fast charging stations on the electric power quality by studying different power quality phenomena such as low-order and high-order harmonics, supraharmonics and voltage/light flickering. New three-phase effective power quantities are …

Planar transformer isolated DC-DC Converter for Solid-State Transformer
The demand for high frequency, high power density and high efficiency on power converters has been increasing through the years. Solid state transformer (SST), which is typically formed by three stages, one being DC/AC inverter, which is controllable, one being medium-frequency transformer isolated …

Controlling Laser High-Order Harmonic Generation Using Weak Counter-Propagating Light
Laser high-order harmonic generation in the presence of relatively weak interfering light is investigated. The interfering pulses intersect the primary harmonic-generating laser pulse at the laser focus. The interfering light creates a standing intensity and phase modulation on the field, which …

Modeling generation and characterization of attosecond pulses
Generation of high-order harmonics has emerged as a powerful technique for the generation of broadband coherent radiation in the EUV regime. This has lead to the development of table-top EUV sources that can produce attosecond pulses. These pulses can serve as a probe to resolve atomic attosecond …

Direct Observation of Laser Filamentation in High-Order Harmonic Generation
… of an intense laser pulse as it generates high-order harmonics in a long gas cell, filled with 80 torr of helium. A thin foil separates the gas-filled region of the cell from a subsequent evacuated region. The exit plane of the gas cell can be scanned along the laser axis so that the …
