Abstract

The Nd3+ --> Yb3+ energy-transfer efficiency in the YAl3(BO3)(4) nonlinear laser crystal has been investigated as a function of both donor (Nd3+) and acceptor (Yb3+) concentrations. An analytical expression giving the value of the energy-transfer rate for any Nd3+ and Yb3+ concentrations has been obtained on the basis of the analysis of experimental data. From this expression, a basic model is proposed to determine the Nd3+ and Yb3+ concentrations that optimize the Yb3+ output laser power obtained from a 808-nm diode-pumped Nd3+; Yb3+: YAl3(BO3)(4) crystal.
