By analyzing the propagation and evolution characteristics of a spiral phase modulated orbital angular momentum (OAM) light field, we propose a new approach to investigate the nonlinear effects of the evolutionary wave source of the optical field. Based on the three-wave coupling model and the Collins path integral theory, we obtain the analytical expressions of the frequency-doubled light and its diffraction propagation solutions of the OAM evolutionary wave source. We experimentally study the propagation property of the second harmonic wave by imaging the OAM evolutionary wave source in the frequency-doubling crystal based on a femtosecond Ti: Al2O3 laser and the 4f coherent system. The frequency-doubling output powers of OAM wave sources with different orders are measured and compared with those of OAM modes after evolution. The research results show that using the starting point of evolution as the nonlinear interaction area can solve the problems such as the low nonlinear interaction efficiency caused by light overlapping and the overlarge spot of a high-dimensional OAM beam. Simultaneously, it provides an important basis for the high-efficiency nonlinear manipulation and control of a high-dimensional OAM light field.
