摘要:

我们演示了实验探索的吸引子图的光学机械系统的光学力补偿的机械损失。在这种情况下,发生稳定的自激振荡,但仅限于特定的镜振幅和激光失谐。我们证明,我们可以放大的机械模式的振幅500倍以上的热振幅在300 K。缺乏不稳定或混沌运动使我们能够操纵我们的系统进入一个非平凡的稳定状态,并探索自激振荡的动力学非常详细。

英文摘要:

We demonstrate experimental exploration of the attractor diagram of an optomechanical system where the optical forces compensate for the mechanical losses. In this case stable self-induced oscillations occur but only for specific mirror amplitudes and laser detunings. We demonstrate that we can amplify the mechanical mode to an amplitude 500 times larger than the thermal amplitude at 300K. The lack of unstable or chaotic motion allows us to manipulate our system into a non-trivial steady state and explore the dynamics of self-induced oscillations in great detail.
