Book excerpt: The report discusses the experimental results and optimization of a relatively high-power, high-efficiency CW gas laser utilizing a dc excited discharge with a flowing combination of carbon dioxide, helium, and nitrogen as the active laser medium. Continuous laser power output of 126 watts has been measured from a system of 4.7 cm diameter by 2.4 meters long. Details of the various cavity configurations, reflector materials, power coupling-out methods and current characteristics of the discharge are discussed. A 90 degree folded design cavity is described including some intra-cavity Q-switching experiments. These experiments are part of a continuing study of the technology concerning design, construction and optimization of CO2 lasers. (Author).

Book excerpt: The report concerns the investigation and optimization of high power and high efficiency in the cw gas laser utilizing carbon dioxide, nitrogen and helium as the active laser medium. In all cases, the gases are excited by an electrical discharge. In the area of flowing gas lasers, an experimental investigation was made into the unsaturated gain characteristics at 10.6 microns and their dependence on the tube diameter, gas mixing, and flow speed. The measurements were taken with a laser bridge of sufficient resolution to measure the radial profiles of the gain. For the high-power oscillators, determination was made of the dependence of the power on tube length, gas pressure, pumping speed, output coupling, and mode control. For sealed-off lasers, determination was made of the dependence of the output power on the gas mix, pressure, and tube preparation. Some results on the initial phases of long life tests are also included. Much of the data which was accumulated indicates that the present limitations of output power in large bore tubes and sealed-off tubes stem from the heating of the gas by the discharge. This is corroborated by theoretical calculations of the heat transfer and temperature profile in the tube. (Author).

This book was released on 2011 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon Dioxide (CO2) laser beam cutting (LBC) process involves several parameters. These parameters need to be optimized in order to get the best quality output. Researchers had applied various types of optimization methods which are used for single or multi-objectives problems. One of the methods is Grey-Taguchi method. However, there is a disadvantage of these methods. This study focuses on improving the Grey-Taguchi method in order to optimize machining parameters for CO2 LBC. The Variable Weight Grey-Taguchi method is proposed which considering all possible weights to be assigned to the control and noise factors. The considered control factors are stand-off distance, cutting speed and laser power. This study also considers surrounding temperature as noise factor. The superior of these methods is merely depending on the response factors which are Surface Roughness (SR), Kerf Taper Angle (TAP), Heat Affected Zone (HAZ) and Kerf Width (KW). Results from Matlab assisted physical experiment shows there is an effect on weight assigning to the factors. Results also show that the proposed method successfull improved all the response factors. Surface roughness had improved by 49.4%, taper 52%, Heat Affected Zone (HAZ) 9.3% and kerf width 46.2%. As conclusion, this study had successfully proposed an improved optimization method for LBC process.
