A number of Dy3+-doped crystals have been studied and spectroscopic and theoretical data suggests that Dy3+:chlorides are promising candidates for amplification of the 1.3 μm signal used by the telecommunications network. In particular, LaCl3:Dy3+ has an emission band centered around 1.3 μm with a radiative lifetime greater than one millisecond which is consistent with a quantum yield above 70% (compared to 3% for Pr:ZBLAN). Gain data from pump-probe experiments at 1.319 μm and 1338 μm resulted in a net gain of 13% and ~14%, respectively.
