采用宽带受激拉曼散射的量子理论，提出“点相关原理”，详细分析了光波导改善宽带多光束拉曼组束效率和光束质量的机制，从理论上分析了波导参数和光束的初始参数对组束效率和性能的影响，并利用最新拉曼组束结果给予了点相关原理的正确性讨论。认为“点相关原理”能够更好地解释波导组束的内在机制． Based on the quantum theory of broadband stimulated Raman scattering, a “point correlation principle” is proposed. The mechanism of the optical waveguide to improve the beam efficiency and beam quality of the broadband multi-beam Raman beam is analyzed in detail. The waveguide parameters and the initial parameters of the beam are analyzed theoretically On the beam-group efficiency and performance, and the correctness of the point-correlation principle is discussed by using the latest Raman beaming results. It is believed that “point-related principle” can better explain the intrinsic mechanism of waveguide bundle.
