Ultrafast Imaging of Optical Damage in PMMA


A new imaging system with ultrafast (75 ps) time resolution, the “picosecond microscope” is used to study the damage dynamics of PMMA irradiated at 532 nm. A small diameter (50 μm), intense laser pulse is used to damage the PMMA, and a larger diameter, delayed probe pulse is imaged onto a video camera detector. The resultant time-dependent images are a “motion picture” of the damage process.
