RESEARCH ACTIVITIES:
Research activities in this laboratory are dedicated to studies of laser-assisted microfabrication, including high power laser ablation and laser micromachining. Experimental studies with nanosecond time resolution are performed to investigate thermal processes that occur on short time and spatial scales during high power laser-material interactions. Processes that are studied include heat transfer, melting, ablation, and fluid flow. Equipment in this laboratory includes two high power Nd:YAG lasers, vibration isolation tables, a 1-GHz bandwidth oscilloscope, fast response optical detectors, and imaging equipment.
CURRENT RESEARCH PROJECTS:
Laser-Induced Forward Transfer (LIFT) and direct write technologies
Thermocapillary flow and rupture during thin film laser micromachining
High power laser ablation and phase explosion
