Optical skyrmions are a recently demonstrated topological state of light that promise a rich set of physics and applications, in particular, material manipulation. In this work, we demonstrate a method to generate these states from a laser, which has an intermediate bimeron state, providing a route to compact, high power, and low cost skyrmion research and applications. We use a praseodymium gain medium to make red (640 nm) and orange (607 nm) Bloch-, Néel-, and anti-skyrmions, with a route to the other visible emission bands of the gain medium. This approach uses a wedged optic as the key component, which could be easily adapted to other laser gain media and laser cavity configurations, and other exotic topological states.

使用楔形输出耦合器的光学斯格明子激光器


光学斯格明子是最近被证明的光的拓扑状态，它有望提供丰富的物理和应用，特别是材料操纵。在这项工作中，我们演示了一种从具有中间双聚子态的激光器产生这些态的方法，为紧凑、高功率和低成本的斯格明子研究和应用提供了一条途径。我们使用镨增益介质来制造红色（640 nm）和橙色（607 nm）布洛赫子、尼尔子和反斯格明子，并有一条通向增益介质的其他可见发射带的路线。这种方法使用楔形光学器件作为关键组件，可以轻松适应其他激光增益介质和激光腔配置以及其他奇异的拓扑状态。
