Abstract :
It is shown that the gain obtainable by coherent amplification using two-wave mixing in BSO crystals is limited by nonlinear effects. A model based on a generalisation of existing theories is presented, giving the dependence of gain coefficient on input beam ratio and leading to good agreement with experimental results.
