Book Description
The purpose of this study is to develop models of pulsed and continuous wave (CW) CO2 lasers on a personal computer, and to explore optimization of the computed output power using response surface methodology (RSM). The first program is based on a four-level point model of pulsed Co2 laser that predicts the temperature rise and the effects of temperature on the power, energy, and gain of the pulsed laser. The second program, derived from the first, is based on a four-level point model of a continuous wave CO2 laser and calculates the power, gain, small-signal gain, and saturation flux of the CW laser. Both models were verified and extensively validated against published data with good results. Finally, this study explored the optimization of the CW laser model using RSM and found an operating point for maximum power at 10 torr and 4% CO2. Several recommendations are included for upgrading the CO2 laser models and continuing the optimization.

Book Description
Abstract: RF excited CO2 lasers are widely used in industry. They provide relatively high power discharge levels while maintaining compactness, simplicity, and durability with respect to other competing laser technologies. To attain high power levels in the range of 5-10 KW, lasers with large electrode areas have to be designed. Unfortunately, due to the large electrode length requirements, transmission line effects make the discharge loading nonlinear, adversely affecting the efficiency of the CO2 laser. A standard approach to linearize the discharge loading is to introduce shunt inductors across the length of the electrodes in an effort to counter the capacitive nature of the discharge behavior. This thesis investigates and improves the theoretical models found in the literature in an effort to predict the discharge non-uniformity and allow for multiple shunt inductors installation. Specifically, we discuss the coupling of a CO2 laser discharge model with an electrical circuit solving scheme and how it can be characterized as one dimensional (1-D) and two dimensional (2-D) systems. The 1-D system is modeled using transmission line (TL) theory, where as the 2-D system is modeled using a finite difference time domain (FDTD) scheme. All our models were implemented in standard MATLAB code and the results are compared with those found in the literature with the goal to analyze and ascertain model limitations.
