摘要
实际的激光腔不可避免有增益介质的存在,同时,也不可能保证光强的泵浦分布是均匀的。这样光强分布的不均匀必然导致增益分布的不均匀,因此,在考虑自再现模时有考虑增益系数分布状态的必要。本文给出数学公式以及若干个增益分布模型的实例验证这种假设的可行性和合理性。
It is inevitable that a gain medium exists always in a practical laser resonator. Moreover, it is impossible to ensure the pump light intensity distribution in the laser medium is uniform. The inhomogeneous distribution of gain coefficient is inevitable because of the inhomogeneous distribution of pump light intensity in laser medium. So it is necessary to include gain coefficient distribution in the resolution of the self-reproducing field pattern. This paper provides math formulas and several instances of models of gain coefficient distribution to validate the feasibility and rationality of this approach to the resolution of self-reproducing field pattern of laser active resonator.
