Defensive laser amplification system

Abstract

A counter high-energy laser system directs high-intensity laser radiation back to a threat laser in the form of an ultra-short optical pulse (USP). The retro-directed USP induces permanent internal optical damage in the threat laser, thus disabling the threat by exploiting the very high optical gain at the source of an incoming laser thereby causing an injected pulse to grow exponentially in energy and peak power within the threat laser optical train until it reaches a damaging threshold. The existing optical energy from the threat laser system and stored in the laser beam from threat system is exploited thereby enabling the size, weight, and power of the counter laser system to be significantly reduced. The wavelength of the counter pulse is automatically matched to the threat.
