How new laser development can help laser shock peening penetration to widen industrial applications?

Abstract

Despite obvious benefits to fatigue behavior of Laser Shock Peened components, this technology is still only applied in very limited cases in aviation and nuclear power industry. Limited number of lasers suitable for this treatment, their cost, size and working conditions are the most limiting factors. In this paper, we propose a new approach in the laser architecture which should overcome mentioned limitations of existing laser sources and as a consequence enable wider application of Laser Shock Peening.
