Advanced Beam Control for Locating & Engagement (ABLE)

What Is It?Beam Control System is responsible for identifying the target, pointing and maintaining the beam at the proper aimpoint, effectively delivering the laser beam (accuracy and atmospheric compensation), assessing a target kill, and rapidly engaging the next target in the cue.

What Does It Offer?An effective beam control subsystem that can be integrated onto a relevant military platform

Goals:• Beam-train loss ≤ 5% (Gaussian laser beam)• Improved tracking and aimpoint maintenance• Enhanced compensation for atmospheric

turbulencePartners: HEL JTO, Army, Navy, Air Force, IndustryTechnical Approach:• Invest in key component development• Build subsystem from components for

demonstrations

Atmospheric Propagation

• The AP TAWG provides environmental framework for ABLE– Facilitates and vets HEL field test campaigns involving JTO funding or endorsement– Conducts "forensic“ analysis to determine HEL propagation effects– Leads propagation effect modeling improvements

• Resolve anomalies and gaps in two problematic atmospheric regions:

– Near surface (1st 100m, both land and sea)– Atmospheric boundary layer top (dynamic

region of max Cn2 and max extinction) JOINT AF, ARMY, NAVY ISSUE

• Leverage emerging sensor capabilities to solve characterization problems

– Digital holography, LIDAR, AIRS, SWIR cameras for image-based r0 measurement

• Determine impact of near-platform atmospheric disturbances

– Aero-optic, compressive flows– Heat island à severe localized turbulence
