Abstract：

The research areas of Professor Lam Yee Cheong are outlined, in particular in the areas of femto-second laser machining and the fabrication of micro-features of aluminum molds. Investigations carried out demonstrated that (a) significant laser energy is conducted away during femto-second laser machining contrary to the common belief that there is no or negligible heat conduction; and (b) features much less that the grain size of a polycrystalline metal could be formed and that grain size is a limiting factor on feature size is only a myth.
