And this is the description of what another team has discovered using the properties of diamonds as well:

Ground-breaking research is harnessing the unique properties of diamonds to develop a new generation of lasers that could lead to many benefits, from better treatment of skin complaints and diabetes-related eye conditions to improved pollution monitoring and aeronautical engineering.

A University of Strathclyde team has developed a new type of high-performance, ultra-versatile Raman laser* that harnesses diamonds to produce light beams with more power and a wider range of colours than current Raman lasers. These capabilities could open up important new applications. The research is funded by the Engineering and Physical Sciences Research Council (EPSRC).

And below are two videos including one in Japan firing the world’s most powerful laser!
