摘要: Abstract A kind of fluorescence around 800–900 nm, 620–650 440–450 nm and 400–420 has been achieved in optical fibres. The first the fourth are related to Ge II others dangling bonds on oxygen. They were all obtained by multiphoton pumping. Similar experiments performed a neodymium-doped core fibre 920 emission dopant was collected. However, species which gives rise non-linear pumping that involved linear appear be different.
