The aeronautic industry is constantly looking for new techniques to save fuel consumption and reduce cost. Utilizing materials with improve strength and reduced density is by far the most efficient way to achieve this goal. New fabrication techniques or a process that reduces the total manufacturing cost is another strategy to reduce the cost of aircraft ownership. The fabrication of aircraft component is labor intense. The techniques that decrease processing time and reduce the use of labor are particularly attractive. In this front, laser material processing has been proved to be competitive, owning to its rapid processing, singlestep operation and versatility. At present, traditional laser systems such as continuous wave (CW) and nanosecond pulsed lasers dominate the aeronautic fabrications. CO2 laser operates at continuous mode with a wavelength of 10.6 Î¼m. This type of laser is the earliest used in aerospace manufacturing. Nd: YAG lasers are primarily of the pulsed type.
