自调制激光韦克菲尔德加速器利用前向拉曼不稳定性驱动大振幅等离子体波。这个过程的有效性可能取决于它如何与其他过程（如自聚焦和空化）或其他不稳定性（如反射和冲洗）竞争。各种过程之间的相对定时取决于每个不稳定性的种子的性质。电离前沿和拉曼反向散射都能够播种前向拉曼不稳定性。这导致前向拉曼不稳定性比预期的要早得多。
The self-modulated laser wakefield accelerator utilizes the forward Raman instability to drive a large-amplitude plasma wave. The effectiveness of this process could depend on how it competes with other processes such as self-focusing and cavitation, or other instabilities such as filamentation and hosing. The relative timing between the various processes is dependent on the nature of the seed for each instability. Both ionization fronts and Raman backscatter are capable of seeding the forward Raman instability. This causes the forward Raman instability to emerge much earlier than would otherwise be expected.
