Abstract
We identify a cloud of plasmon-resonant particles as an ultimate low-power third-order nonlinear-optic medium that may be suitable for configuring large holographic optical elements in space. We compute the third-order susceptibility and the saturation power density of such a cloud in a space environment. We find that electrostatic repulsion of the particles because of charging by the background plasma dominates as the effective internal pressure of the cloud. The pump-power density required for configuring a space hologram in a cloud of plasmon-resonant particles for 100-μm radiation under ideal conditions is computed to be ~1 W/m2 for a background plasma density and an electron temperature of 108 cm−3 and 1 eV, respectively. The scaling behavior of the pump-power density with the radiation wavelength and the cloud thickness is exhibited and compared with results for nonresonant particles.
