nonlinear optical (NLO) active
devices was prepared by utilizing stereolithographic three-dimensional
printing technique. Microcrystalline NLO active component, urea, or
potassium dihydrogen phosphate was dispersed in a simple photopolymerizable
polyacrylate-based resin and used as the printing material to fabricate
highly efficient transparent NLO lenses. The nonlinear activity of
the printed lenses was confirmed by second-harmonic generation measurements
using a femtosecond laser-pumped optical parametric amplifier operating
at a wavelength of 1195 nm. The three-dimensional printing provides
a simple method to utilize a range of NLO active compounds without
tedious crystal growing and processing steps. Furthermore, introducing
NLO additives in the printing material provides an easy and cost-efficient
way to manufacture lenses with NLO functionality.
