论文摘要
我们提出了一个可调节的声子激光原型，该原型带有大型被困的离子阵列，其中一些离子被光晶镊子有效地固定，从而隔离了一个模仿用作声子激光谐振器的原声腔的子集。然后可以通过镊子强度和“壁厚”（固定离子的数量）来控制空腔损失。我们通过施加蓝色边带激光器来泵送谐振器，并研究腔模式的激光动力学，例如阈值行为，种群分布，二阶相干性和线narrow的光谱。该方案可以推广到由由几个离子形成的多个腔模式组成的谐振器，在该模式下，我们演示了模式竞争和同步，并且随着激光模式的发展。
We propose a tunable phonon laser prototype with a large trapped ion array, where some of the ions are effectively pinned by optical tweezers, thus isolating a subset of ions that mimics an acoustic cavity used as a phonon lasing resonator. The cavity loss can then be controlled by the tweezer strength and the "wall thickness", the number of pinned ions for isolation. We pump the resonator by applying blue-sideband lasers, and investigate the lasing dynamics of the cavity modes such as threshold behavior, population distribution, the second-order coherence, and line-narrowed spectrum. This scheme can be generalized to resonators consisting of multiple cavity modes formed by a few ions, where we demonstrate mode competition and synchronization as lasing modes have developed.
