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.
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.
