| Abstract: | Properties of the four-level avalanche upconversion system are carefully investigated using a rate equation analysis of the equilibritlm state.It is clarified that avalanche upconversion would open only when pumping laser strength and cross-relexation are bigger than a threshold level.The population variations of every energy level upon the cross-relexation and transition rates are given in this paper. |
