Low temporal coherence pulse can effectively increase the threshold of parametric instabilities in the laser and plasma interaction. However, frequency conversion efficiency is one of the bottlenecks in its engineering application. The characteristics of frequency conversion technologies of various low-coherence pulse for the high-power laser drivers are summarized in this paper, and based on numerical simulations and experiments, application feasibility of partial deuterium DKDP crystals for frequency doubling and tripling of super-luminescent light are analyzed in detail. The results show that 17% deuterium DKDP crystals can be used for efficient frequency doubling of super-luminescent light in neodymium glass systems, and the conversion efficiency can reach about 80%. 10% gradient deuterium DKDP crystals can be used for triple frequency of 5 THz bandwidth.
