abstract

• We report on the interaction of high repetition rate (MHz) Ti: sapphire laser pulses with a spiropyran polymer (MIC1). Such a polymer is photochromic, wich has potential applications in integrated optical devices. A thin film of polymer deposited on a glass substrate is irradiated with ultrashort pulses (66 fs) from a Ti: sapphire laser. We demonstrate that it is possible to induce an absorption band in the visible by the use of femtosecond pulses via a two-photon excitation process; this might be useful to accomplish waveguide-like structures formation with photochromic response. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
