摘要:	非線性引發的現象已經在不同的領域裡有了相當多的研究，在這篇的論文中以微粒電漿為背景及脈衝雷射為工具，來產生電漿微泡。進而以電漿微粒做微觀測其電漿微泡的動力行為，首次以實驗中觀測到電漿孤立子的出現及運動行為，而在延續調控實驗參數使電漿中非線性的特性產生波動現象。 Nonlinearity-induced instability are observed in many different branches of physics. Also, strongly coupled coulomb clusters are contained richly nonlinear phenomena, which are well developed in past few years in our lab. Dust particles are negatively charged inside plasma, since electrons have higher mobility than ions in plasma. Therefore by introducing plume, which is generated by focused pulse laser into dusty plasma, we present a plasma bubble in the plasma system, which has long life time as cavitation bubble in water. To the extent of the system condition, instability waves are also observed.
