加载时间是磁光陷阱最重要的动态特性之一。在本文中，我们主要报告了一些磁光陷阱控制参数对加载时间影响的详细实验研究，包括背景真空压力、磁场梯度以及捕获和再泵浦激光的强度。我们将结果与先前的理论和实验结果进行比较，并给出定性分析。这些实验研究为控制磁光陷阱的加载时间提供了一些有用的指导。实现的可控加载时间有助于提高光缔合光谱的信噪比，信噪比从7显着提高到28.6。
Loading time is one of the most important dynamic characteristics of a magneto—optical trap. In this paper, we primarily report on a detailed experimental study of the effects of some magneto—optical trap control parameters on loading time, including the background vacuum pressure, the magnetic field gradient, and the intensities of trapping and repumping lasers. We compare the results with previous theoretical and experimental results, and give qualitative analysis. These experimental investigations offer some useful guidelines to control the loading time of magneto—optical traps. The controllable loading time achieved is helpful to enhance the signal-to-noise ratio of photoassociation spectroscopy, which is remarkably improved from 7 to 28.6.
