N2  - Aluminum alloys are important structural materials because of their  high strength to weight ratio. Unfortunately, due to their high  reflectivity and complexity in heat treatment, aluminum alloys are  some of the hardest metals to be laser treated successfully and very  high laser power is usually required. In the present work detailed  study of the interaction of laser light with a special aluminum alloy  (containing zeolite) compared with pure aluminum is presented. The  inclusion of zeolite material inside the aluminum alloy gives the alloy  expandable volume under compression.  Three lasers have been used throughout the present study. An  Nd:YAG laser (1064 nm), with pulse width in nanosecond scale,  which has the maximum absorption coefficient with aluminum alloy,  and two femtosecond lasers; Ti:sapphire laser source (800 nm), and  Satsuma laser source (1030 nm). This makes it possible to study the  effect of both the laser wavelength and the pulse duration on the  interaction mechanisms as well as the LIBS analysis
