N2 - In this paper we try to investigate theorically the effect of chromium concentration on efficiency of Nd,Cr:GSGG laser. For this purpose we use current models for drawing luminescence decay of chromium and obtaining lifetime of chromium in present of interaction with other ions. Thus we calculate rate of nonradiative energy transfer between ions, then we calculate the number of excited acceptor ions and efficiency of energy transfer from donors to acceptors. M3 ER -
