In this paper we describe the use of single-mode optical fibres to deliver moderate-power, but very high beam quality Nd:YAG light for precision machining, at peak powers of 300 W in 0.1 ms pulses. An example application is demonstrated: the cutting of 0.05 and 0.2 mm thick stainless steel sheet with kerf widths and feature sizes as small as 30 μm.
