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…
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…
Transition between mechanisms of laser-induced field-free molecular orientation
Irina Znakovskaya, Michael Spanner, Sankar De +6
The transition between two distinct mechanisms for the laser-induced field-free orientation of CO molecules is observed via measurements of orientation revival times and subsequent…
Carrier-Envelope-Phase Dependent Dissociation of Hydrogen
Han Xu, J - P Maclean, D E Laban +4
We studied dependence of dissociative ionization in H2 on carrier-envelope phase (CEP) of few-cycle (6fs) near-infrared (NIR) laser pulses. For low-energy channels, we present the…
Field-free orientation of CO molecules by femtosecond two-color laser fields
S. De, I. Znakovskaya, D. Ray +8
We report the first experimental observation of non-adiabatic field-free orientation of a heteronuclear diatomic molecule (CO) induced by an intense two-color (800 and 400 nm) femt…
