The present invention relates to a laser guided and powered directed energy weapon that combines two different lasers to accurately and efficiently deliver a high energy electromagnetic pulse (EMP) to a target at long range. The method uses a high energy laser pulse with relatively long pulse duration focused in air to create a plasma ball which emits an intense EMP. Typically the long pulse duration of high energy lasers would severely limit focal accuracy and effective range because of air pressure variations and pollutants in the atmosphere. However the present invention uses a second ultrafast laser to create a long thin optical plasma filament between the variable location of the plasma ball and the target to act as a stable electrical connection or conducting wire. Consequently EMP can be efficiently channeled to the target via the optical filament, thereby dramatically increasing potential accuracy, range and energy delivery efficiency.
