Researchers make an RGB laser with a regular laser and quantum dots

| May 27, 2012

The riddle with lasers is, they tend to bring about just a single color or irradiate.To get more than one tinge requires actually combining more than united type of laser to produce red, undecayed and blue. But researchers at Brown University consider figured out a solution to creating paltry RGB lasers by using colloidal quantum dots, or CQDs. The pattern of leveraging the properties of the scanty film isn’t new, but past attempts to use CQDs in semiconductor lasers be seized of failed because the necessary energy tends to breath up as heat instead of fickle. The work around scientists found was to awaken the various dot sizes with a laser that time filter out original light source. Unfortuneately, the breach is far from practical for appliance in commercial products, but it does depict a milestone in the march towards a one only-material multi-wavelength laser.
