2Physics Quote:
"Lasers are light sources with well-defined and well-manageable properties, making them an ideal tool for scientific research. Nevertheless, at some points the inherent (quasi-) monochromaticity of lasers is a drawback. Using a convenient converting phosphor can produce a broad spectrum but also results in a loss of the desired laser properties, in particular the high degree of directionality. To generate true white light while retaining this directionality, one can resort to nonlinear effects like soliton formation."

ITER's Tokamak

The most advanced approach to fusion involves
using magnetic fields to confine the deuterium
–tritium plasma. This is the route to be taken by
International Thermonuclear Experimental
Reactor (ITER), which will build a fusion reactor
at Cadarache in the south of France [ITER is an
international coallition among China, the European
Union (EU), Japan, Russia, South Korea and the
US]. The project will cost $10 billion to build and
run. ITER will use magnetic fields generated by
superconducting coils to confine a plasma of
deuterium and tritium in a donut-shaped chamber
called a Tokamak. The plasma will be heated to a temperature of 100
million degrees so that the deuterium and tritium nuclei can overcome
their mutual repulsion and undergo nuclear fusion.

I read this for a while, and I suppose my physics has yet to be so good that I could understand the concepts behind. It would be helpful if charts or figures could be used. I am more visual.
