The suppress effect of TWM upon the incident beamfanning in large signal is presented and the effect of the beamfanning on the output of the signal are discussed theoretically.
The light amplification mechanism of fanning noise in doped lithium niobate crystals was analyzed and the light amplification competition between the signal beam and the fanning noise was discussed.
分析了掺杂铌酸锂晶体的扇形噪声光的形成机制,讨论了信号光与扇形噪声光之间的光放大竞争问题。
