Abstract

Composite films containing solid state laser nanoparticles have been created which show optical amplification in the technologically important near IR range. The solid state laser materials studied, Cr-forsterite (Cr-Mg2SiO4) and Cr-diopside (Cr-CaMgSi2O6), were prepared using a dispersion polymerized polymer precursor. The nanoparticles produced during the polymer synthesis acted as size templates, creating fine crystalline powders of the Cr-forsterite and Crdiopside upon calcination. These fine powders were dispersed in a refractive index matched polymer matrix and cast as 5–10 μm thick films. The resulting composite containing Cr-forsterite showed optical amplification of 300 dB/m at 1.24 μm.
