Research on TEA Metal Vapor Lasers

金教授在美国国家科学基金会（NSF）资助下的研究项目ECS-8300505导致了铜蒸气激光器快速横向放电激发的高温技术的发展。这种金属蒸汽激光器在绿色和黄绿色光谱区域发射，在材料加工和超短脉冲技术的应用中非常有用。目前的工作将致力于高平均功率、高重复率横向铜蒸气激光器的发展，包括激光动力学和泵浦机制的研究。在观测Dicke超辐射现象时，PI还将尝试通过光抽运铜蒸气系统来产生相干辐射。

Research conducted by Professor Kim under NSF grant ECS-8300505 has led to development of high temperature technology for fast transverse electrical-discharge excitation of copper vapor lasers. Such metal vapor lasers, emitting in the green and green-yellow spectral region, are useful in applications of materials processing and ultrashort pulse technology. The current work will pursue development of high average power, high repetition-rate transverse copper vapor lasers, including investigations of the laser kinetics and pumping mechanisms. The PI will also attempt to generate coherent radiation by optical pumping of the copper vapor system in an attempt to observe Dicke superradiance phenomena.
