Atoms Interacting with Electromagnetic Fields, Multiphoton Ionization
The non linear interaction between an intense laser radiation and atoms leads to ionization through the absorption of N photons from the laser radiation via laser-induced virtual states. The multiphoton ionization rate varies as a function of the laser intensity I as IN. We discuss the two most important effects which govern multiphoton ionization processes : resonance effects and laser-coheren...

متن کاملOn-off Attitude Control Using Pulse-width Pulse-frequency Modulated Input Shaper
Kinetic kill vehicle (KKV) is actuated by on-off thrusters to adjust its attitude, how to modulate continuous control commands to on-off or pulse signals to meet the requirements of the thrusters is a challenging task. Pulse-width pulse-frequency (PWPF) modulation is an effective method that provides pseudolinear operation for on-off thrusters. In this work, a new thruster configuration of the ...
متن کاملTheory of Gas Ionization by Intense Electromagnetic Fields
The distribution function of the electrons produced in the interaction between an intense electromagnetic wave and a neutral gas is derived and is shown to be nonequilibrium and anisotropic. By assuming that the time scale of gas ionization is much greater than the field period, it is shown that the electron distribution function formed in microwave and optical discharges has sharp anisotropy a...
