Interest in developing airborne laser systems has been pursued in the United States since the Airborne Laser Laboratory (ALL) in the late 1970s and early 1980s. The ALL program was very successful; however, it was believed that in order to increase the capability of airborne laser systems, a shorter wavelength laser needed to be used.

In this webinar hosted by the Laser Systems Technical Group, Matthew Kalensky will introduce aero-optics and the challenges these environments impose. The remainder of the webinar will focus on one specific aero-optical effect: shock waves. Here, the effects of shock waves on both the pupil plane phase as well as the image-plane irradiance pattern will be introduced.

What You Will Learn:
• Overview of aero-optical effects
• Introduction to the fluid mechanics of shock waves
• Effects of shock waves on a laser beam and Shack-Hartmann wavefront sensor measurements

Who Should Attend:
• Individuals interested in aero-optics
• Individuals interested in optical diagnostics for high-speed flows
• Individuals interested in wavefront sensing

About the Presenter: Matthew Kalensky from the Naval Surface Warfare Center Dahlgren Division

Matthew received his PhD in aerospace engineering from the University of Notre Dame. While there, he was a member of the aero-optics group where he worked on many beam control-related problems. In addition to M&S and lab testing, Matthew was heavily involved in the Airborne Aero-Optics Laboratory. Matthew now works at the Naval Surface Warfare Center Dahlgren Division in the Optics & Beam Control branch of the Integrated Engagement Systems department. Here, he continues research into many problems related to beam control, deep turbulence compensation, and aero-effects.
