Dissimilar joining of shape memory alloy to other materials may find interesting applications in the microelectronics and medical devices, allowing for innovative designs and further miniaturization of parts and devices. Femtosecond laser has been investigated to join NiTi to glass aiming at to assess to which extent NiTi particles will deposit on glass when irradiated by a femtosecond laser beam. This is a non thermal process and the irradiated areas were observed under SEM with EDS to analyze the morphology of the deposits and changes in the chemical composition. The results show that NiTi can be bonded to glass by femtosecond laser irradiation. Deposited particles show a micrometric granular structure.
