We demonstrate, for the first time, the direct generation of a bottle beam with a well-isolated three-dimensional zero-intensity dark core (high potential barrier) from a compact intracavity frequency-doubled Nd:YVO laser with a nearly hemispherical cavity. We also numerically calculate the physical properties of the generated bottle beam using a coherent superposition of a series of frequency-locked Laguerre-Gaussian modes.
我们首次展示了利用一个具有近半球形腔的紧凑型腔内倍频Nd:YVO激光器直接产生具有良好隔离的三维零强度暗核（高势垒）的瓶形光束。我们还使用一系列锁频拉盖尔 - 高斯模式的相干叠加，对所产生的瓶形光束的物理特性进行了数值计算。
