The European Union has initiated the phased restriction of cadmium (Cd). As a result, it is becoming increasingly interesting to look for safer laser alternatives to helium-cadmium (HeCd) lasers.

This article outlines the principles and practical benefits of SERDS and discusses the laser requirements essential for reliable performance.

As magnetic materials gain increased importance for information technology, the characterization of spin waves is moving into the focus of scientists. In this case, the magnetic properties of such materials are especially of interest and Brillouin light scattering spectroscopy (BLS) is then the prefect technique to investigate with.
