Presentation Title MM-4: Direct Visualization of Ultrashort-pulse Laser-based Materials Processing with Ultrafast Transmission Electron Microscopy

On-Site Speaker (Planned) Chang Wan Han
Abstract Scope Over the last decade, lasers have been widely adopted in synthesizing novel nanomaterials: functional thinfilms, such as complex oxides are grown with the pulsed laser deposition (PLD). Ultrafast laser ablation has been utilized to synthesize functional nanoparticles in liquid medium. Despite the wide-range usage of ultrafast lasers in materials processing, a direct visualization of the interaction between the laser pulses and the materials at the nanoscale, which is crucial to understand the physics governing the dynamics during the laser processing, has been so far limited because ultrafast interactions between the laser pulses and the materials occur at a the time-scale not accessible by conventional electron microscopy. However, the development of ultrafast photoemission electron sources opens the possibility of visualizing ultrafast dynamic processes at the nanoscale by Ultrafast Transmission Electron Microscopy (UTEM). The obtained results with the direct visualization of ultrafast laser-based material processing using UTEM technique will be presented.
