Visualizing TPP structures with coherent Raman scattering microscopy

Abstract
The chemical and physical processes that take place in the sub-μm3 volume of the tightly focused laser beam during TPP writing are complex. Variations in photon flux, exposure time, heat dissipation kinetics, and concentration of photoinitiator and monomer can give rise to differences in the properties of the polymer material, such as the degree of conversion, density, and mechanical properties. Quality control of the TPP process, especially in terms of the chemical conversion during and immediately after laser illumination, is highly desirable. Alongside developments in TPP writing techniques, the detailed chemical in situ characterization of TPP structures plays an equally important role in driving the technology toward maturation.
