Want To Deploy Optimized Directed Energy Weapons? Integrate A Compact Noise Source

Additive white Gaussian noise (AWGN) generation is an effective way to combat Stimulated Brillouin Scattering (SBS) in directed energy weapons (DEW). SBS reflects a significant, high-power fraction of the incident light beam back toward the laser source, which limits DEW from reaching their power output potential.

AWGN negates this effect by spreading laser coherence. The process involves reducing each laser module's peak power while preserving average power to maintain the required output of the entire system. The best AWGN generating device for a specific laser system depends on its stage of development.

This post takes a closer look at an ideal AWGN solution to reduce SBS in finalized DEW systems.
