Analysis of the scaling laws about focused uniform beam spreading induced by real atmosphere

By using the method of numerical simulation and experimental observation, focused uniform beam spreading induced by atmospheric turbulence and thermal blooming is analyzed. The scaling relations between the laser propagation effects and characteristic parameters described atmospheric propagation effects are obtained. Based upon these scaling relations, we can efficiently estimate atmospheric propagation effects and learn the performance of a particular system design for various environmental conditions as well as for conducting laser system design optimization.
