研究了无芯光纤的扩束效应对超小梯度折射率光纤探头聚焦性能的影响，以期优化此类探头的光学性能。以探头聚焦性能（包括工作距离和聚焦光斑尺寸）与无芯光纤长度的变化关系为判据，基于高斯光束的基本性质，计算了超小梯度折射率光纤探头中无芯光纤的有效扩束长度。分别通过数值计算和实验测量进行了验证和分析。结果表明，加入无芯光纤可以有效增加超小梯度折射率光纤探头的工作距离，但会导致聚焦光斑尺寸增大。在所研究的光纤探头参数下，无芯光纤间隔棒的有效扩束长度小于0.357 mm。
The light-beam expansion effect of a no-core fiber on the focusing performance of an ultra-small gradient-index fiber probe is investigated with a view to optimizing the optical performance of such probes. By taking the variable relationship between the focusing performance (including the working distance and the focusing spot size) of the probe and the length of the no-core fiber as the criterion, the effective beam expansion length of the no-core fiber in the ultra-small gradient-index fiber probe is calculated based on the basic properties of the Gaussian beam. Verification and analysis are done by numerical calculations and experimental measurements, respectively. The obtained results show that the working distance of an ultra-small gradient-index fiber probe can be increased effectively by adding a no-core fiber; however, this will lead to increasing the focusing spot size. For the parameters of the fiber probe studied here, the effective beam expansion length of the no-core fiber spacer is less than 0.357 mm.
