Course 3.  Atmospheric Propagation of High Energy Lasers

Classification: Unclassified

Instructor:
    -  Dr. Phillip Sprangle, Naval Research Laboratory

Duration: Half-day course, starts at 0800

CEUs awarded: 0.35

Course Description and Topics: This course addresses the key physical processes that affect the propagation of high energy lasers (HELs) in the atmosphere. One of the objectives of this course is to discuss the optimum laser wavelength and power for efficient propagation in various atmospheric environments, i.e., maritime, continental, urban, etc. The processes which contribute to laser beam spreading and intensity loss include: thermal blooming, turbulence, aerosol/molecular scattering and absorption, aerosol heating/vaporization, and laser beam quality effects. Aerosols, which consist of water, sea salt, organic matter, dust, soot, biomass smoke, urban pollutants, etc, are of particular importance because they result in laser scattering, absorption and enhanced thermal blooming. Those aerosols which can not be vaporized, such as those consisting of dust, soot, etc, can significantly enhance thermal blooming. HELCAP (High Energy Laser Code for Atmospheric Propagation) is a fully 3-D, time dependent code that is suitable for studying and characterizing the atmospheric propagation of HEL beams. HEL propagation in the atmosphere is illustrated by HELCAP simulations covering a range of wavelengths, pulse formats and atmospheric conditions. The course will also address issues of adaptive optics relevant to the propagation of high energy laser beams. Though it is a critical technology for any laser system, adaptive optics has both fundamental and technological limitations which will be discussed.

Intended Audience: This course is intended to present an overview of the various physical processes which affect the propagation of HEL laser pulses in the atmosphere. Scientists, engineers and managers should have a good science background.

Instructor Biography: Dr. Phillip Sprangle is Chief Scientist and Head of the Beam Physics Branch at the Naval Research Laboratory.

Course Description and Topics: This course will be presented at the FOUO level. This course reviews laser material interactions over parameter ranges of interest for weapons applications. Fundamental considerations of the optical coupling of the laser energy into the material will be presented. This will be followed by physics-based treatments of the response of metals, organic-based materials, and ceramics to the laser irradiation.

  • Metals: Simple cw, one-dimensional treatments will be utilized to illustrate the general principles of the response of metals to laser radiation, but two-dimensional cases, phase changes, and pulsed effects will be discussed as well.

  • Organic Based Materials: The effects of high energy laser (HEL) radiation on organic based materials, including fiber reinforced composites, plastics and coatings will be reviewed. Materials will range from char formers and charring ablators to clean ablators. The relationship between the pyrolysis processes taking place in various materials during HEL radiation will be reviewed as a function of material composition, form and structure.

  • Ceramic Materials: Considerations of the response of ceramic shapes when laser loading is added to in-service stresses will be presented. An understanding of these responses from models, which are based on a combination of the thermo-mechanical stress calculations and statistically based fracture initiation, will be presented.

Intended Audience: To best profit from the course, students should have a basic understanding of chemistry and physics at the college undergraduate level. Managers of technical programs as well as technical persons conducting or planning to conduct laser experiments will benefit from the course and should emerge from the experience with a broadened technical perspective. As a result of participating in this course, students should have a better understanding of the structure and composition of materials and how their properties determine the way in which high energy lasers (HEL) interact with and result in damage to these materials. Students will acquire an increased understanding of the mechanisms of interaction of various laser pulse forms and wavelengths with diverse types of materials.

Course 6.  SHARE/HELEEOS Scaling Law Models

Classification: Unclassified, For Official Use Only, Export Controlled

Instructors:
    -  Dr. Matthew Whiteley, ATK Mission Research Corporation
    -  Dr. Eric Magee, ATK Mission Research Corporation
    -  Richard Bartell, Air Force Institute of Technology
    -  Lt Col Steven Fiorino, Air Force Institute of Technology

Duration:Full-day course, starts at 0800

CEUs awarded: 0.7

Course Description: This short course provides an introduction to both the Scaling for HEL and Relay Engagement (SHARE) toolbox for MATLAB developed by ATK Mission Research Corporation and the High Energy Laser End to End Operational Simulation (HELEEOS) scaling law engagement model developed by the Air Force Institute of Technology (AFIT) Center for Directed Energy. The class will consist of an overview of general issues involved in developing scaling law models and the assumptions underlying the calculations followed by discussions of the major features of each of the models. HEL performance for a common example scenario will be estimated in class using each of the models.

SHARE was developed for the Air Force Research Laboratory Directed Energy Directorate to address diverse HEL system concept modeling, including the application of high-altitude or tactical relay systems. Examples will illustrate the process of establishing atmospheric model assumptions, system parameters, and engagement geometries from which target irradiance characteristics are computed by the SHARE functions. Methods for performing parametric analysis of systems and target engagements will be reviewed. Interfacing of SHARE functions and calculations with other toolbox or custom MATLAB functions/scripts will also be discussed.

HELEEOS has been developed, under sponsorship of the HEL Joint Technology Office, to support a broad range of analyses applicable to the operational requirements of all the military services. The model's results can be presented as interactive nomographs allowing the user to explore the parameter space in detail. Probability of kill (Pk) is the HELEEOS' primary metric. A key feature is the ability to evaluate uncertainty in low-altitude engagements due to geographical spatial-temporal variability in all major clear-air atmospheric effects. Atmospheric parameters available for investigation include correlated profiles of temperature, pressure, water vapor content, relative humidity, aerosols, and optical turbulence.

Students should bring their laptops to class for installation of the model software and user guide.

Topics

  • Fourier optics fundamentals
  • Optical system performance assessment
  • Origin and derivation of propagation scaling laws
  • Atmospheric modeling
  • HELEEOS tutorial/demonstration: tactical laser scenario
  • SHARE tutorial/demonstration: tactical laser scenario-direct and relay

Intended Audience: This course is intended for technical staff and technical managers desiring a working knowledge of the nature of scaling-law models for concept exploration, system design studies, and performance evaluation. Students will be introduced to the process of performance modeling for tactical high-energy laser systems using both the HELEEOS and SHARE codes. It is the intent of the instructors to make both models available in advance to qualified persons registered for this class. The instructors recommend that the software be installed on a student-owned laptop prior to the class date. Computer workstations will not be provided by DEPS. Students without laptop computers and installed software may attend the course, but will not be able to follow the code examples in a "hands-on" manner.
