Optical, structural, and lasing properties of a composite material nanoporous glass filled with an organic dye-activated polymer

Structural and optical characteristics of polymer-filled nanoporous glass (PFNPG) composite was studied with holographic interferometry and atomic-force microscopy methods. A high homogeneity of the bulk PFNPG samples and their surfaces has been found. Light scattering in the samples was investigated. Rather low scattering losses have been observed in spite of heterogeneous structure of the composite. This result is discussed on a base of the Rayleigh scattering model. Lasing properties including a pump-to-laser conversion efficiency and a life time due to photodestruction of PFNPG samples activated with pyrromethene dyes are reported.
