Ultra-fast femtosecond (fs) lasers provide a unique technological opportunity\nto precisely and efficiently micromachine materials with minimal thermal damage\nowing to the reduced heat transfer into the bulk of the work material offered\nby short pulse duration, high laser intensity and focused optical energy\ndelivered on a timescale shorter than the rate of thermal diffusion into the\nsurrounding area of a beam foci. There is an increasing demand to further\ndevelop the fs machining technology to improve the machining quality, minimize\nthe total machining time and increase the flexibility of machining complex\npatterns on diamond. This article offers an overview of recent research\nfindings on the application of fs laser technology to micromachine diamond. The\nlaser technology to precisely micromachine diamond is discussed and detailed,\nwith a focus on the use of fs laser irradiation systems and their\ncharacteristics, laser interaction with various types of diamonds, processing\nand the subsequent post-processing of the irradiated samples and, appropriate\nsample characterisation methods. Finally, the current and emerging application\nareas are discussed, and the challenges and the future research prospects in\nthe fs laser micromachining field are also identified.\n
