The field of rare-earth-doped fibre lasers and amplifiers has expanded rapidly in recent years and there are now numerous publications in the area. A variety of glass hosts, dopants and pump sources have been used, with the goal of achieving low-threshold, diode-laser-pumped operation of fibre lasers and amplifiers, particularly those operating in either the second or third telecommunication windows. While much of the commercial interest is likely to be in the area of optical communications amplifiers and sources based on Er3+ and Nd3+, it is also important to realise that five other rare earths have successfully been incorporated into silica hosts and operated as fibre lasers, namely samarium, praseodymium, ytterbium, thulium and holmium
