Lasers in 10 years time!!!!

[benthegeek]

Very interesting Ben, but due to their small size , can a Quantum dot produce a wavelength of light greater than its actual size? (excuse my ignorance on the subject) :-[ By that I mean Lasing and not Flourescence.

Bah, first of all (not to you), someone tell the moderators to turn the no link posting shit off! Third time I have had to rewrite a post because this forum software REFUSES to let me remove the links from the post I made. It just deletes it. Half an hours typing gone. Thank out non existant God that that Microsoft invented Ctrl-C. My post is as follows:

I had to look this up myself, but yes. Typical sizes are on the order of 2-10nm yet produce light in the visible range (400-700nm) with ease. Not unreasonable when you consider atoms themselves eit such long wavelength radiation. I don't believe anyone has made a working laser out o them yet though, I think it may have something to do with manufacturing instabilities, making consistantly similar prticles at that size is hard.

Now, as for the deep-UV dvd player, it would work if you could find an optical material that is transperent to deep UV light and is strong enough to withstand the force of everyday dvd use. Even then, it would have to compete with emerging data storage technologies:

Holographic Data Storage: h t t p : / / en.wikipedia.org/wiki/Holographic_data_storage
3D Optical Data Storage: h t t p : / / en.wikipedia.org/wiki/3D_optical_data_storage
Nano-particle Enchanced Optical Data Storage: h t t p : / / w w w . swinburne.edu.au/feis/cmp/research/nanophotonics.html

All three can offer storage into the Terabyte range rather than the Gigabyte range that current 2D Optical Data stoage offers. Swinburne uiversity, my university worked on 3D storage and now is working on Nanoparticle enhanced storage.
