摘要：
Light emission from the 1G4 --> H-3-5 transition around 1.3-mu-m of Pr3+ has been studied in fluoride glass (ZBLAN) fibres. Pumping at 1064 nm yields extracted laser power of a few mW at 1.294-mu-m. Gain curves centred at 1.295-mu-m have been obtained, with gross gains of more than 15 dB at 1.319-mu-m. Changes of the output ASE with pumping conditions are explained by excited state absorption or energy transfer from the 1G4 upper level of the transition.
