Abstract The combination of nanoporous optical thin films prepared by the sol-gel process with direct-write capabilities has been an area of interest over the past decade. Recent advancements in both fields suggest the possibility of fabricating novel components for rapid prototyping purposes. This paper presents the work in progress done over the past year, initially aimed at process characterization. Standard silicate sol-gels were synthesized and deposited by spin coating on silicon wafers. Further post processing was done prior to laser densification with a CO2 laser.
