Abstract:

We have measured upconversion fluorescence resulting from the excitation of room temperature 1 and 5 ErYAG by a 1532 nm nanosecond pump source. Measurements of the fluorescence decay from the 4I132, 4I112, 4F92 and 4S32 manifolds to the 4I152 ground state manifold were observed over a wide range of excitation pulse fluence values. A unique set of upconversion parameters were extracted from the measurements using a modification of the traditional rate equation model. Results of calculation are compared to measurement.
