The system is compact, readily transportable, and provides a robust, tunable output suitable for long range studies of high intensity laser propagation. The supporting testing infrastructure, which includes stand-alone beam diagnostic stations and atmospheric monitoring capabilities, makes this facility ideal for the development of stand-off high energy ultrafast applications and fundamental studies of atmospheric laser science.This work is supported by the ARO MURI program “Fundamental Filamentation Science,” a DURIP entitled “MU-HELF, a mobile ultrafast high energy laser facility,” the HEL/JTO MRI “Fundamentals of filamentation interaction,” the ARO MURI “Light filamentation science,” and the State of Florida.
