Over recent years the powers that can be achieved from fibre lasers have grown rapidly due to parallel advances in the high-power semiconductor laser diodes used to energize fibre lasers, diode-to-fibre coupling schemes and doped fibre design and fabrication. Whilst the headline results have generally related to the possibilities of scaling continuous-wave fibre lasers, with 10kW now possible from an effectively single-mode core, advances in many aspects of pulsed laser performance have been just as spectacular. For example, using the fibre Master Oscillator Power Amplifier (MOPA) approach it is now possible to realise fs and ps pulsed fibre systems operating at the multi-100W level with pulse energies in excess of the 1 mJ level. In the nanosecond regime multi-100W systems have also been achieved with single mode pulse energies of several mJ, and by relaxing the mode-quality higher pulse energies are now possible.
