These short courses were offered in
conjunction with the Fifth Annual Directed Energy Symposium.
Continuing Education Unit (CEU) credits were offered for completion of these DEPS short courses.
Free-Electron Laser Short Course
Instructors:
- Prof. Patrick O'Shea, University of Maryland
- Prof. William Colson, Naval Postgraduate School
- Dr. George Neil, Thomas Jefferson National Accelerator Facility
This Free-Electron Laser (FEL) short course will offer a general introduction to FELs including basic
physics and technology concepts, major worldwide projects, and applications. Design considerations of
high average power FELs will be discussed, covering electron beam, optics and undulator designs. The
course will end with a practical implementation of high average power FELs, including overall system
configuration, systems efficiency, power sources, control, and operation.
Schedule:
0800 FEL Accelerator Design Considerations (O'Shea)
1000 Break
1030 FEL Undulator Design Physics (Colson)
1230 Lunch
1330 FEL Systems Design (Neil)
1530 Adjourn
High Power Microwave Technology Short Course
Instructors:
- Prof. James Dickens, Texas Tech University
- Dr. James Benford, Microwave Sciences, Inc.
- Prof. Michael Morgan, Naval Postgraduate School
This course provides a three-part tutorial on state-of-the-art high power microwave technologies.
Via these three parts, attendees will be exposed to both the historical perspective as well as the
present state of the various components that comprise a high power microwave system. Each of the
following will be covered in an individual two-hour block: the development of pulsed power and its
applications to microwave generation, narrowband high power microwave source technology, and the
fundamental principles of antennas for high power microwave sources. Attendees should have a
background in science or engineering at the B.S. level to receive the most benefit from the course.
Schedule:
0800 Pulsed Source Technology (Dickens)
1000 Break
1030 Narrow Band HPM (Benford)
1230 Lunch
1330 HPM Antenna Design Considerations (Morgan)

Beam Control Short Course
Instructors:
- Dr. Paul Merritt, The Boeing Company SVS, Inc.
- Dr. Tim Howard, The Boeing Company SVS, Inc.
- Mr. Dick Brunson, The Boeing Company SVS, Inc.
This class will present the basic material needed to design and analyze a laser pointing and tracking
system from target acquisition through fine pointing. The topics will include performance equations,
radiometrics, the acquisition process, image processing, track algorithms, and gimbal pointing. The
course will stay focused on technical topics and useful equations.
Schedule:
0800 Introduction (Merritt)
0900 Radiometry (Howard)

Laser Propagation and Materials Interaction Short Course
Instructors:
- Prof. Donald Walters, Naval Postgraduate School
- Dr. Phillip Sprangle, Naval Research Laboratory
- Dr. Jorge Beraun, Air Force Research Laboratory
This course will provide an introduction of atmospheric laser propagation by first describing the
principles of scattering, absorption, turbulence and wind for typical laser beams of greater than
10-10 second duration. Next, propagation processes associated with short, intense laser pulses will
be discussed. The diverse linear and nonlinear effects on optical propagation will be described.
Finally, the processes of laser beams interaction with solid matter will be presented.
Schedule:
0800 Classical Laser Propagation (Walters)
1000 Break
1030 Short Pulse Propagation (Sprangle)
1230 Lunch
1330 Laser Interaction Physics (Beraun)
1530 Adjourn
Introduction to Directed Energy and Current Technical Issues Short Course
Instructors:
- Dr. Al Kehs, Army Research Lab
- Mr. John Albertine, Independent Consultant, Navy DEW program
This course will provide an introduction to the field of directed energy weapons. It is geared to
the undergraduate student, graduate student or engineer/scientist entering the DE field.
The introduction to HPM weapons will follow the history of early excitement and crude experiments
to the more refined modeling and simulation-based programs that characterize current activity.
Generic effects and applications will provide perspective for discussions on technology that will
include both narrow band and ultra-wide band sources, antenna fundamentals, propagation, diagnostics,
modulators, power sources, and an introduction to hardening devices and techniques. Current modeling
and simulation tools will also be presented as appropriate. The HEL field will be introduced using an
interleaving of history, technical requirements, and accomplishments. The basic attributes of HEL
weapons will be covered, leading into discussions of laser-material interaction, lethality, potential
applications, system requirements, laser power scaling, propagation and beam control. Current
technical issues and areas of research emphasis will be highlighted.
Schedule:
0800 High Power Microwave Systems (Kehs)
1000 Break
1030 High Energy Laser Systems (Albertine)
1300 Adjourn
