论文摘要
我们介绍了挤压激光的概念，其中挤压腔模式由于刺激的发射而发展出宏观光子占用。在激光阈值上方，发射光既保留激光固有的光谱纯度，又保留了带有挤压四倍体的光子模式的光子相关特征。我们的建议可以在光学设置中实施，依赖于腔体驱动的参数驱动以及宽带挤压真空的耗散稳定。挤压激光器可以找到超出标准激光器的应用，这要符合标准的特征，例如超出标准量子限制的米歇尔森干涉法中的直接应用或在原子计量学中的使用。
We introduce the concept of a squeezed laser, in which a squeezed cavity mode develops a macroscopic photonic occupation due to stimulated emission. Above the lasing threshold, the emitted light retains both the spectral purity inherent of a laser and the photon correlations characteristic of a photonic mode with squeezed quadratures. Our proposal, which can be implemented in optical setups, relies on the parametric driving of the cavity and dissipative stabilization by a broadband squeezed vacuum. The squeezed laser can find applications that go beyond those of standard lasers thanks to the squeezed character, such as the direct application in Michelson interferometry beyond the standard quantum limit, or its use in atomic metrology.
