Single nanomaterial yields many laser colors

PROVIDENCE, R.I. [Brown University] — Red, green, and blue lasers have become small and cheap enough to find their way into products ranging from BluRay DVD players to fancy pens, but each color is made with different semiconductor materials and by elaborate crystal growth processes. A new prototype technology demonstrates all three of those colors coming from one material.

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

Technology / Gadgets : Engadget (3 years ago)

The problem with lasers is, they tend to generate just a single color or light.To get more than one hue requires actually combining more than one type of laser to produce red, green and blue. But researchers at Brown University have... Read Post

Single nanomaterial yields many laser colors

Academics / General Science : Science Daily (3 years ago)

Engineers have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays. The size determines color, but all the pyramid-shaped quantum dots are made the same way of the same e... Read Post

Engineers produce multiple colors of lasers using a single material

Technology / Gadgets : Gizmag (3 years ago)

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. ... Read Post
