光-声Laser(移相器)泵浦系统非线性特性的几点注记
Some Remarks on Nonlinear Properties of Pumping System of an Optical-Wavelength Acoustic Laser (Phaser)
摘要:
本文对光波长声激光器(相位器)双泵浦系统的三维矢量模型进行了分析,找到了新的临界面。对于泵浦谐振器的高品质因数Qc,在上分支处的该泵浦系统的李雅普诺夫不稳定性是可能的:Qc/Qm >> 1,其中Qm是磁品质因数。这种不稳定性对解释红宝石相位器的某些实验数据很有意义(见我们以前的论文arXiv:cond-mat/0303188,arXiv:cond-mat/0402640,arXiv:0704.0123,arXiv:0901.0449)。
英文摘要:
New critical surfaces have been analytically found for a 3D vectorial model of bistable pumping system of an optical-wavelength acoustic laser (phaser). The Lyapunov instability is possible for this pumping system at the upper branch for a high quality factor Qc of a pump resonator: Qc/Qm >> 1, where Qm is the magnetic quality factor. This instability is of great interest for interpretaion of some experimental data on the optical-wavelength ruby phaser (see our previous papers arXiv:cond-mat/0303188, arXiv:cond-mat/0402640, arXiv:0704.0123, arXiv:0901.0449).
