FIG. 1.

Spectral dependence of the absorption coefficient for a film sample before (solid curve) and after (dotted curve) curing. The nanoparticle-dispersed sample contains nanoparticles and initiator. The dash-dotted curve corresponds to a least-squares fit of the Rayleigh scattering formula to the data in the range of 400–650 nm.

FIG. 7.

Recording dynamics of for samples at various concentrations of nanoparticles. The estimated effective thicknesses were 12, 15, 12, 12, and for samples at 20, 25, 30, 35, and of nanoparticles, respectively.

FIG. 8.

Dependences of (a) and (b) recorded and probed at (◻) 404 and (○) 535 nm on concentration of nanoparticles. The recording intensities were 5 and at 404 and 532 nm, respectively.

Dependences of (a) and (b) on recording intensity for transmission volume holograms recorded and probed at (◻) 404 and (○) 535 nm.

Image of FIG. 10.
FIG. 10.

Incident-angle dependences of transmittance after incoherent (dotted curves) and coherent (solid curves) uniform exposure. Coherent laser beams at 404 nm (curves in gray) and 532 nm (curves in black) were used as probe beams.
