标题： Two-photon superbunching of pseudothermal light in a Hanbury Brown-Twiss interferometer

摘要： 双光子超束流伪热光在直线光学系统中用单模连续波激光光观察到。 通过添加更多双光子路径，利用三个旋转的研磨玻璃，实验上观察到g(2)(0) = 7.10。 对超束流伪热光的二阶时间相干函数进行了理论和实验的详细研究。 预测通过添加更多多光子路径可以显著提高光的相干度。 例如，使用五个旋转的研磨玻璃的超束流伪热光的二阶和三阶相干度分别可达32和7776。 这些结果有助于理解超束流的物理机制，并提高热光鬼成像的可见度。 显示英文摘要

摘要： Two-photon superbunching of pseudothermal light is observed with single-mode continuous-wave laser light in a linear optical system. By adding more two-photon paths via three rotating ground glasses,g(2)(0) = 7.10 is experimentally observed. The second-order temporal coherence function of superbunching pseudothermal light is theoretically and experimentally studied in detail. It is predicted that the degree of coherence of light can be increased dramatically by adding more multi-photon paths. For instance, the degree of the second- and third-order coherence of the superbunching pseudothermal light with five rotating ground glasses can reach 32 and 7776, respectively. The results are helpful to understand the physics of superbunching and to improve the visibility of thermal light ghost imaging.
