Laser-Induced Graphitisation of Diamond Under 30 fs Laser Pulse Irradiation
Bakhtiar Ali, Han Xu, Dashavir Chetty +3
The degree of laser-induced graphitisation from a sp3-bonded to a sp2-bonded carbon fraction in a single crystal chemical vapour deposited (CVD) diamond under a varying fluence of…
Observation of Dynamic Stark Resonances in Strong-Field Excitation
Dashavir Chetty, Rohan D. Glover, Bruno A. deHarak +12
We investigate AC Stark-shifted resonances in argon with ultrashort near-infrared pulses. Using 30 fs pulses we observe periodic enhancements of the excitation yield in the intensi…
Relativistic non-dipole effects in strong-field atomic ionization at moderate intensities
Nida Haram, Igor Ivanov, Han Xu +7
We present a detailed experimental and theoretical study on the relativistic non-dipole effects in strong-field atomic ionisation by near-infrared linearly-polarised few-cycle lase…
Experimental observation of the elusive double-peak structure in R-dependent strong-field ionization rate of H2+
Han Xu, Feng He, D. Kielpinski +2
When a diatomic molecule is ionized by an intense laser field, the ionization rate depends very strongly on the inter-nuclear separation. That dependence exhibits a pronounced maxi…
