| description | In this paper, an efficient cascaded sum frequency generation (SFG) model based on Stark-chirped rapid adiabatic passage is established, in which the laser of signal, intermediate, and output corresponds to three primary, and an approach of white laser source synthesis is proposed. The research results show that the energy of the red laser can be almost converted into blue laser, while the green laser intensity is extremely low in the cascade SFG process. The farther away from the optimal coupling delay parameters, the smaller the corresponding conversion efficiency is. Meanwhile, the pump intensity has a larger control range for conversion efficiency. On the basis of these findings, a white laser source with a color temperature of 6500 K can be synthesized. We first roughly adjust the pump intensity to reduce the conversion efficiency so that the red, green and blue lasers coexist at the output. Then, we fine-tune the coupling delay parameters so that the output power ratio meets 0.61:0.28:0.11. These research results can provide a theoretical basis for achieving efficient frequency conversion and the development of new optical devices. |
