Abstract

Even though gold nanorod doped dielectrics have been widely used for optical laser writing and patterning there has been no attempt to study the dynamic range of these nanocomposites, let alone exploring ways to improve this property. Here we study the dynamic range of a gold nanorod doped polyvinyl alcohol film for various laser spot sizes at two different laser pulse repetition rates and show that when a high repetition rate laser source is employed the dynamic range of the nanocomposite is severely limited due to accumulative heating inside the focal volume. This problem could be solved by silica-coating the nanorods inside the polymer matrix. This method does not compromise the high repetition rate of the laser writing source and yet retains the attractive flexible properties of the polymer matrix. The silica-coated gold nanorod doped polymer nanocomposite could be an attractive medium for future high-speed, high repetition rate pulsed laser writing and patterning applications.
