Teensy weensy lasers

[steve001]

Researchers have found a way to convert nanoparticle-coated microscopic beads into lasers smaller than red blood cells.
These microlasers, which convert infrared light into light at higher frequencies, are among the smallest continuously emitting lasers of their kind ever reported and can constantly and stably emit light for hours at a time, even when submerged in biological fluids such as blood serum.

Interesting... What could they be used
for ??

Why did I post a link?

I wonder what the divergence would be, if collimated.... hmmm...

Simple. You bioengineer these into sharks.

So sorry.... I didn't click on the link...
Sorry to have bothered you with my question...
Your time must be much more valuable than mine...:cryyy:

Again I apologize for my question without first clicking

Now they will have to figure out how to make nano laser goggles as well

Sorry... I didn't read the manual... :undecided:

I read the entire link yesterday. Though they are interesting, what they will be useful for remains to be seen. The fact that this was found completely by accident while making nano particles for other purposes seems to show it is an answer waiting for a question. I don't see these as being used for collimated beams, but a source of visible light with a relatively narrow line width.

All is forgiven.
