论文摘要
当泵波矢量和线性极化分别沿$ [110] $和$ [1 \ bar {1} 0] $轴时，我们证明了在钻石中与随机线性偏振的相干stokes脉冲的产生。在这种配置中，多种拉曼模式的激发产生各向同性增益，防止Stokes脉冲获得确定性取向，而是通过晶体的零点运动随机分组。实验极化测量与独立的，相同的分布一致，估计每个脉冲6.67位。
We demonstrate the generation of coherent Stokes pulses with randomized linear-polarization in diamond, when the pump wave-vector and linear polarization were oriented along the $[110]$ and $[1\bar{1}0]$ axes respectively. In this configuration the excitation of multiple Raman modes produces isotropic gain, preventing the Stokes pulse from acquiring a deterministic orientation and is instead randomized by the zero-point motion of the crystal. Experimental polarization measurements were consistent with an independent, identical distribution with an estimated entropy rate of 6.67 bits per pulse.
