The radiative recombination from one end of a streamer in high gain GaAs photoconductive semiconductor switches （PCSS） was analyzed. First, the radiative recombination coegicient of monochromatic light （890 nm） was proposed. The equation of spontaneous radiation of the monochromatic light was deduced. The computed results were well consistent with the reported experimental observations. This demonstrates that the model of the spontaneous radiation from the tip of the streamer is reasonable.
