Paper Abstract

Directional Infrared Countermeasures (DIRCM) is an effective technique to defeat heat-seeking missiles. The major problem of existing DIRCM is that it may work like a beacon for threats that are not susceptible to the jamming code implemented: attracting a missile instead of re-directing it away from the aircraft. Ultra-fast laser pulse technology is discussed as an alternative to a conventional laser DIRCM. An ultra-fast laser is capable of providing a different type of countermeasure which is compatible with existing laser based DIRCM pointing systems as it requires much less peak power than damage inducing systems. A foundation of ultra-fast technology is its unique ability to alter the intrinsic characteristics of the semiconductor. In this paper, we will only consider the effects of a mild lattice disturbance caused by relatively low energy ultra-fast (femto-second) and, to some extent, fast (pico-second) laser pulses.
