色散对单模激光系统非线性效应的影响

Effect of dispersion on nonlinear effect in single mode laser system

研究在强光场的作用下 ,激光系统中的腔内介质的折射率不再是常数而引起的非线性效应 ,即色散型激光系统的动力学行为。研究结果表明 ,这类系统的输出场会呈现双稳态 ,并利用极值法确定了描述这类色散型激光系统的Maxvell-

It is discussed that for strong optical field the refractive index of the medium in the cavity of a laser system is no longer constant, which gives rise to the nonlinear effect, i e the dynamical bahaviour of the laser system with dispersion The result indicates that the output optical fielt of this kind of system will show bistability The extreme method is used to determine the critical point of parameter and the bistability region of the Maxwell Bloch equation which describes laser systems with dispersion
