The probability density of the single-shot mean Stokes frequency from a linear Raman generator is calculated. It is shown that the fluctuations in the Stokes pulse energy spectrum that arise from the quantum initiation of the Stokes light are reduced in the transient regime of amplification. Also, it appears that saturation of the Raman gain does not reduce the phase fluctuations of the Stokes light below those present in the unsaturated gain (linear) regime.
计算了线性拉曼发生器单次平均斯托克斯频率的概率密度。结果表明,在放大的瞬态过程中,由斯托克斯光的量子产生引起的斯托克斯脉冲能谱中的涨落会减小。此外,拉曼增益的饱和似乎并不会使斯托克斯光的相位涨落低于不饱和增益(线性) regime 中存在的涨落。
