The symphony of colours and light flashes generated during laser machining attest to the dramatic undulating physics evolving rapidly as material is transformed through various states of matter, heated to sun-like temperature, shocked to explosive pressure, and finally ejected at supersonic velocity. Understanding and controlling such complex phenomena at ultrashort pulse duration is a major scientific challenge. The interaction physics is poorly understood but promise substantial benefit to steer wanton laser processes into nano-scale manufacturing methods for a new generation of medical, bio-sensor and Telecomm products.

在激光加工过程中产生的色彩和闪光的交响乐证明了戏剧性的起伏物理发展迅速，因为材料经过各种物质状态的转变，加热到太阳般的温度，冲击到爆炸压力，最后以超音速喷射。在超短脉冲持续时间下理解和控制这种复杂现象是一项重大的科学挑战。人们对相互作用的物理学知之甚少，但它有望为新一代医疗、生物传感器和电信产品的纳米级制造方法带来巨大的好处。
