Energetic, tunable, highly elliptically polarized higher harmonics generated by intense two-color counter-rotating laser fields Open
In this work, we demonstrate experimentally the efficient generation and tunability of energetic highly elliptical high harmonics in Ar gas, driven by intense two-color counter-rotating laser electric fields. A bichromatic beam tailored by…

Generation of Energetic Highly Elliptical Extreme Ultraviolet Radiation Open
In this study, the generation of energetic coherent extreme ultraviolet (XUV) radiation with the potential for controlled polarization is reported. The XUV radiation results from the process of high harmonic generation (HHG) in a gas phase…

4H-SiC VJFETs with Self-Aligned Contacts Open
Trenched-implanted-gate 4H–SiC vertical-channel JFET (TI-VJFET) have been fabricated with self-aligned nickel silicide source and gate contacts using a process sequence that greatly reduces process complexity as it includes only four litho…
