研究一个激光脉冲放大器增益通量的模型.利用广义变分迭代方法,首先决定Lagrange乘子,然后构造迭代关系式.最后得到了相应模型近似解.
The model for gain fluence of a laser pulse amplifier is studied.Firstly,using the generalized variational iteration method,the Lagrange multipicator is determined.Then the iteration expansions are constructed.Thus approximate solutions for the corresponding model are obtained.
