Abstract:
An analysis, using a single-phase-sheet model, of the effect of an oscillating thermally bloomed atmosphere on a high-power laser beam is presented. The oscillations are caused by a small modulation of the wave front of the beam at the transmitter. The primary contention made here is that the time-dependent blooming is not an oscillating version of its static counterpart; rather, new gratinglike effects are introduced by the interaction of the crosswind and the dithered high-power beam. The resulting temporal variations of the target-plane irradiance at the position of its static bloomed peak are examined and implications for slow dither are discussed.

Temperature Dependence on Reaction Rate
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...
