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.

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

Sony today announced that it has developed a high-power, short-wavelength red semiconductor laser array diode, ideal for use as a light source in projection devices. In order for red semiconductor laser array diodes to be used in pr... Read Post

Single nanomaterial yields many laser colors

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

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 ... Read Post
