受激拉曼散射 (SRS) 的强非线性动力学状态由激光散斑图案的确定性强时间调制和空间扰乱技术控制，称为不均匀持续时间和延迟的尖峰序列 (STUD) 脉冲 [B. Afeyan 和 S. Hüller（未发表）]。动力学模拟表明，与具有相同平均强度和相当带宽的随机相位板或诱导空间非相干光束相比，正确使用 STUD 脉冲可将 SRS 反射率降低一个数量级以上。
Stimulated Raman scattering (SRS) in its strongly nonlinear, kinetic regime is controlled by a technique of deterministic, strong temporal modulation and spatial scrambling of laser speckle patterns, called spike trains of uneven duration and delay (STUD) pulses [B. Afeyan and S. Hüller (unpublished)]. Kinetic simulations show that the proper use of STUD pulses decreases SRS reflectivity by more than an order of magnitude over random-phase-plate or induced-spatial-incoherence beams of the same average intensity and comparable bandwidth.
