Inorganic Laser light

[jos]

new material presents efficient and degradation-resistant laser emission in the blue, a spectral region of interest in applications such as spectroscopy or materials processing, among others.The new borane laser material shows a resistance against degradation that is superior or similar to many of the commercially available state-of-the-art blue laser dyes. This high resistance against degradation means that the number of times the liquid medium has to be replaced is reduced, helping to solve issues with costs, occupational hazards and environmental impact due to handling of solvents, which are toxic and flammable.
