Research activities in this laboratory are dedicated to studies of laser-assisted microfabrication, 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. Major equipment in this laboratory includes a high power Nd:YAG laser, an ultraviolet Nd:YLF laser, a Nitrogen laser-pumped dye laser, vibration isolation tables, a 1-GHz bandwidth oscilloscope, fast response optical detectors, and imaging equipment.
