<title>Laser equipment development and laser-matter interaction investigations at Havana University</title>

The research projects at the Laser Technology Laboratory of Havana University are devoted to Nd:YAG lasers development and to the implementation of new laser applications in different fields. Relative to the lasers research the objective is the development of compact, light and relative low-cost lasers. This development is based on a vertical integration strategy that establishes the own elements production as pumping cavities, multilayer mirrors and filters, power supplies control units and others. Several investigations are carried out using these lasers: thin film deposition of semiconductor, ferroelectric and magnetic materials by laser ablation, subsurface laser marking of transparent materials, pulse laser surface silicon texturing and laser cleaning of art works.
