Tomographic Imaging of Molecular Orbital with High Harmonic Generation

High harmonics produced in aligned molecules contain structural information of bound-state electronic states. We have produced high harmonics from N₂ molecules aligned in two orthogonal directions. The projeeted ...

Tomographic imaging of molecular orbitals

Single-electron wavefunctions, or orbitals, are the mathematical constructs used to describe the multi-electron wavefunction of molecules. Because the highest-lying orbitals are responsible for chemical proper...

Modified Abrasives based on fumed SiO₂ and Al₂O₃ for the Cu CMP Process

New abrasive particles based on SiO₂ and Al₂O₃ were produced with different coating and do**. Seven specifically designed particles were dispersed to prepare slurries for Cu CMP. Glycin was used as complexing a...

Controlling High-Harmonic Generation via Molecular Alignment

The yield of high harmonic generation with N₂ and O₂ molecules is enhanced when the molecules are aligned parallel to the laser field that produces the harmonics and suppressed for the perpendicular case, compare...

Optimal control of two-photon transitions: bright and dark femtosecond pulses designed by a self-learning algorithm

Coherent quantum control of the nonresonant 3s-5s excitation in sodium is demonstrated. ”Bright” or ”dark” pulses are designed by an evolutionary algorithm which evaluates a signal from the experiment to contr...

Optimal control of one- and two-photon transitions with shaped femtosecond pulses and feedback

This paper reports two pump–probe experiments in sodium where dynamically tailored ultrashort pulses from a Ti:Sapphire-pumped optical parametric amplifier were employed. The first study focuses on the one-pho...
