«The hard part now is to combine all the advantages of the system and fulfill prerequisites such as high photon indistinguishability, high temperature operation,
increased photon flux and out coupling efficiency that would make them work,» Olbrich said.

Electrical engineers at the Vienna University of Technology (TU Wien) together with researchers from Berlin have drastically
increased the
flux of X-ray
photons using a newly developed mid-infrared laser system.
If this fraction is large, the expected
photon flux increases.
In general, so long as there is some solar heating beneath some level, there must be a net LW + convective heat
flux upward at that level to balance it in equilibrium; convection tends to require some nonzero temperature decline with height, and a net upward LW
flux requires either that the temperature declines with height on the scale of
photon paths (from emission to absorption), or else requires at least a partial «veiw» of space, which can be blocked by
increasing optical thickness above that level.
Increase the
flux in, the sample warms until it is in equilibrium and then there will be sufficient CO2 molecules with an energy state high enough to shoot out as many
photons as are coming in.
So in the Earth surface up there will be a reasonable
flux of 15um
photons which can be absorbed to
increase the active population.
