Characterization of Shear Strength and Bonding Energy of Laser Produced Welding Seams in Glass

energy absorption. In this method ultrashort laser pulses, at a wavelength transparent to the processing material, are tightly focused onto the common interface of two glass pieces and absorbed via nonlinear interaction mechanisms, such as multi photon absorption. In this work we present recent results on the measurements of the shear strength and bonding energy for a number of laser welded soda-lime glass samples produces under different experimental conditions. We demonstrate that the shear strength and the bonding energy are affected differently by the processing parameters and present a qualitative explanation of the observed results.
