Efficient Photoionization-Loading of Trapped Cadmium Ions with Ultrafast Pulses [PDF]
Atomic cadmium ions are loaded into radiofrequency ion traps by photoionization of atoms in a cadmium vapor with ultrafast laser pulses. The photoionization is driven through an intermediate atomic resonance with a frequency-quadrupled mode-locked Ti ...

3D angle-independent Doppler and speckle tracking for the myocardium and blood flow
A technology based on velocity ratio indices is described for application in the myocardium. Angle-independent Doppler indices, such as the pulsatility index, which employ velocity ratios, can be measured even if the ultrasound beam vector at the moving ...
