Laser Guided and Laser Powered Energy Discharge Device

摘要

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.

主权项

1. A dual-laser based method of accurately and efficiently directing energy through the atmosphere over a significant range towards an intended target, said method comprising the steps of;
using an ultrafast laser source, capable of producing a laser pulse with sub-nanosecond pulse duration, combined with focusing optics to create a stable long thin optical plasma filament in the atmosphere with its farthest end physically connected or very close to the target; using a second different high energy laser source, capable of producing a laser pulse with much higher pulse energy than the ultrafast laser source but with significantly longer pulse duration, combined with focusing optics to create a high energy plasma ball in the atmosphere that is positioned at some physical point along the long optical plasma filament, so that the two plasmas spatially and temporally overlap; using the stable optical plasma filament to direct, guide or channel energy from the high energy plasma ball to the target, including but not limited to energy emitted from the plasma ball in the form of an electromagnetic pulse (EMP); and using the directed energy to cause damage to the intended target or any of its components, such that the target is either destroyed, damaged, disabled or disorientated in some manner.
