Engineers produce multiple colors of lasers using a single material

3 years agoTechnology / Gadgets : Gizmag

Ordinarily, if you wanted to include blue, green and red laser light sources in the same device (such as a BluRay player), you would need to built in three separate lasers – each one incorporating different semiconductor materials. Now, however, engineers from Rhode Island’s Brown University have succeeded in creating different colors of lasers, all using the same nanocrystal-based semiconductor.
