Laser Diagnostics for Hypersonics and Directed Energy

Laser Stream in the Laser Diagnostics and High-Speed Combustion Lab.

Laser diagnostics for hypersonics and directed energy research at the George H.W. Bush Combat Development Complex focuses on the maturation and application of novel energetic methods to provide revolutionary performance capabilities.

The objective is to develop and implement laser technologies for hypersonic and directed energy applications.

Adaptive optics

Texas A&M University researchers are working on a system to counteract laser refraction by using adaptive optics. Astronomers developed adaptive optics to clear the clutter out of telescopic images. Sophisticated, changeable mirrors correct for distortions in the atmosphere, sharpening the images until observers can see fine details of faint objects.
