论文摘要
镁的类似激光作用将是一个感兴趣的主题，对于研究非线性木蛋白旋转型至关重要。在这里，我们演示了基于铁磁性绝缘体球体中布里鲁因光散射的磁杆激光行为，该球体支持光学耳语库模式和镁共振。我们表明，激发的木魔在传统上扮演了斯托克斯波的作用，并且在布里渊散射过程中被相干放大，从而使木蛋白激光成为可能。此外，可以通过调整外部磁场来操纵刺激的激发木元数，并随输入光功率呈指数增长。除了提供对磁光相互作用的洞察力外，对镁激光作用的研究还将有助于开发用于处理旋转波激发的新技术，并可能影响磁铁以外的科学领域。潜在的应用范围从准备相干磁通源到操作OnChip功能磁性设备。
An analogous laser action of magnons would be a subject of interest and is crucial for the study of nonlinear magnons spintronics. Here, we demonstrate the magnon laser behavior based on Brillouin light scattering in a ferrimagnetic insulator sphere which supports optical whispering gallery modes and magnon resonances. We show that the excited magnon plays what has traditionally been the role of the Stokes wave and is coherently amplified during the Brillouin scattering process, making magnon laser possible. Furthermore, the stimulating excited magnon number increasing exponentially with the input light power can be manipulated by adjusting the external magnetic field. In addition to providing insight into magneto-optical interaction, the study of magnon laser action will help to develop novel technologies for handling spin-wave excitations and could affect scientific fields beyond magnonics. Potential applications range from preparing coherent magnon sources to operating onchip functional magnetic devices.
