We have demonstrated that the method works over small areas and that it does not lead to significant dopant diffusion.
By keeping the dopant level sufficiently low, opacity should not broaden the lines either.
The spectral window is controlled in order to enhance the contrast between the matrix and the dopant in the fiber.
With these deposition methods, the desired gradients in dopant levels are accomplished by varying the dopant deposition rate as the ablator thickness increases.
Placement of these dopant profiles has been demonstrated.
At this stage, a few beryllium shells with graded dopants were made but research on surface finish and characterization of the dopant levels is ongoing.
The chlorine dopant provides a measurement that should be much less sensitive to opacity effects.
The first two of these three designs are produced by deposition of the ablator material and dopant on a mandrel.
Moreover, the existence of carbon dopant in the foam can ensure laser absorption rates at an admissible level greater than 80%.
Using special polymerisation procedures and surfactant dopants, the obtained polyaniline powder can be made dispersible and hence useful for practical applications.
