Acrylate and metacrylate monomers were obtained from Sartmer (ethoxylated bisphenol A dimethacrylat SR349) and Esschem (urethane dimethacrylate X 850. ethoxylated bisphenol A dimethacrylate X 970, bisGMA X 950). Thick films were cast on glass slides from neat mixtures, and thin films were obtained via spin coating from a dioxane solution.

Experiments have also been conducted successfully with a mode-locked Ti sapphire pumped with a 5 W Millennia laser (Spectra Physics), affording 780 nm light with a 80 fs pulse width, 0.3 W average power, and 88 MHz repetition rate. Polymerization does not occur when operating in continuous wave (cw), only when mode-locked (fs pulses).
