Overview

Research

Research Interests

Research Interests include high power and ultrashort laser development and laser-plasma interactions and applications in sensing, materials processing and laser fusion energy. These studies span more than 40 years. As a visiting scientist I spent five years total at the National Research Council of Canada, three years at the Max-Planck-Institut fuer Quantenoptik in Germany, one year at the CELIA laser institute in Bordeaux and half a year at the Center for High Power Lasers, CLPU, in Salamanca, Spain. During those periods I worked with a large variety of laser systems including high power nanosecond carbon-dioxide, iodine and glass lasers, picosecond glass and krypton fluoride lasers, and femtosecond titanium sapphire laser systems. With these systems I’ve studied a number of high temperature plasma phenomena including x-ray generation, MeV to GeV particle acceleration and hydrodynamics of laser produced plasmas. Many of the studies are related to the ultimate goal of generating fusion energy using high power laser pulses.

Current Research:

  • Relativistic Laser Plasma Interactions and Fast Ignition for Laser Fusion Energy
  • Shock Ignition for Laser Fusion Energy
  • The development of high power femtosecond laser systems
  • MeV to GeV particle acceleration with ultrashort laser pulses
  • The study of laser-plasma interactions on a femtosecond and picosecond time scale including high intensity particle and x-ray generation and applications to laser fusion
  • Laser sensor technology for identification and characterization of materials 
  • Precision micromachining and nanomachining using femtosecond laser pulses  
  • Development of high energy proton telescope for use on proposed satellite mission 

Courses

ECE 341 - Analytical Methods in Electrical Engineering

Introduction to analytical solutions of partial differential equations, eigenfunctions and eigenvalue problems, special functions in cylindrical and spherical coordinates, Green's functions, and transform methods. These concepts provide the necessary mathematical foundation for understanding and analyzing important physical phenomena encountered at the micro and nanoscales. Examples drawn from electromagnetics, quantum mechanics, solidstate physics, photonics, thermal transport, and microelectromechanical systems. Prerequisites: ECE 240 or E E 238, and MATH 309 or 311. Credit may be obtained in only one of ECE 341 or E E 323.
