Laser for surface cleaning

A compact Nd YAG laser suitable for LIBS application and for laser cleaning of surfaces; it evaporates dirt without affecting substrate by means of high-power laser pulses. It is portable and robust.

Er:YAG Laser

An Erbium YAG laser developed to be used for improving the foliar uptake of agrochemicals by plants. For this approach, the Er:YAG laser induces the wax exfoliation which improves the efficiency of capture, drastically reducing the environmental impact of agrochemicals.


SLIT LIBS is a high precision instrument capable of performing an elemental micro-analysis of any material. As an excitation source, it uses a compact monolithic laser which can work without any optical alignment maintenance. The device also includes a time delay in order to make the analysis at different stages of plasma evolution. All of this coupled with a slit-lamp microscope with micrometric aiming control for precise analysis of small samples.
