Ultrafast microscopy and ultrafast calorimetry studies of laser polymer ablation

Research output: Contribution to journalConference articlepeer-review


Laser polymer surface ablation is used in a variety of materials applications. However, little is known about the fundamental mechanisms of laser ablation. We have developed a model ablation system, consisting of a near-infrared (near-IR) dye embedded in a polymer, where the mechanism of ablation is purely photothermal. This system has been studied in detail using ultrafast optical microscopy. Dyes which function as molecular optical thermometers have been embedded in the polymer, permitting the use of precise optical calorimetry to study its thermal decomposition. The practical applications of this model system in imaging science, where it is used in high speed formation of highresolution, high fidelity, dry color images, are discussed.
