We present a novel approach for Stimulated Raman Scattering (SRS) spectroscopy in which a hyper spectral resolution and high-speed spectral acquisition are achieved by employing amplified offset-phase controlled fs-pulse bursts. We investigate the method by solving the coupled non-linear Schrödinger equations and validate it by numerically characterizing SRS in molecular nitrogen as a model compound. The spectral resolution of the method is found to be determined by the inverse product of the number of pulses in the burst and the intraburst pulse separation. The SRS spectrum is obtained through a motion-free scanning of the offset phase that results in a sweep of the Raman-shift frequency. Due to high spectral resolution and fast motion-free scanning the technique is beneficial for a number SRS-based applications such as gas sensing and chemical analysis.

我们提出了一种受激拉曼散射（SRS）光谱的新颖方法，其中通过采用放大的偏移相位控制的飞秒脉冲突发来实现超光谱分辨率和高速光谱采集。我们通过求解耦合非线性薛定谔方程来研究该方法，并通过对作为模型化合物的分子氮中的 SRS 进行数值表征来验证该方法。发现该方法的光谱分辨率是由突发中的脉冲数量和突发内脉冲间隔的倒数乘积决定的。SRS 频谱是通过对偏移相位进行无运动扫描而获得的，从而产生拉曼频移频率的扫描。由于光谱分辨率高和快速无运动扫描，该技术有利于许多基于 SRS 的应用，例如气体传感和化学分析。
