This paper reviews basic relationships and parameters as well as recent trends in research and development of Laser Beam Machining (LBM), particularly emphasising on applications of novel, short and ultra-short pulsed lasers. Since laser development a lot effort has been done to improve laser performance and to limit its drawbacks. One of the main development directions are the improvement of LBM surface integrity by limitation of heat affected zone and the increase of machining accuracy particularly in micromachining. Therefore the machining needs are the main drivers for development of short and ultrashort pulsed lasers that, iasers of better beam quality, lasers of shorter wavelengths. Shorter pulses of the order of 10-15 s enable to minimise heat conduction and maximise ablation, whereas shorter wavelengths (< 300nm) are absorbed too a greater extent by the material rather than longer wavelengths. Moreover shorter wavelengths enable to produce smaller features. This paper gives also a number of various laser machining applications as well as considers modern laser beam guidance techniques.
