✦ Synopsis

The Yb 3+ to Er 3+ energy transfer in yttrium aluminum borate (YAB) crystal is investigated with the rate equation without considering the back energy transfer. The energy transfer coefficients (W 25 ) in the crystals with different Yb 3+ concentrations are determined and compared with those in other crystals. The transfer efficiencies and the micro-parameters of energy transfer and migration are also determined. The results show that the energy transfer from Yb 3+ to Er 3+ in YAB crystal is very efficient and the Yb 3+ -Er 3+ co-doped YAB crystal may be a good candidate for the 1.55 lm laser media.
