摘要	Featured Application Plasma mirrors, as terminal pulse-cleaning elements, have displayed excellent performance in improving the temporal contrast of ultrashort high-power lasers. However, their temporal contrast enhancement measurement is complicated and challenging. Due to their single-shot feature, the measurements of the temporal contrast using traditional delay-scanning methods are inapplicable, while applicable single-shot methods would require a significant cost to achieve the temporal contrast of 10(12) or better, just for measuring the enhancement of 2-3 orders of magnitude. In this manuscript, we focused on the temporal contrast enhancement measurement of a single plasma mirror by a chirped pulse. It relies on a single-shot spectral measurement of a chirped pulse overlapped spatiotemporally with the igniting laser pulse used to produce the plasma mirror. This method has good potential for the online measurement of the temporal contrast enhancement of plasma mirrors. We focused on a single-shot method for directly measuring the temporal contrast enhancement of a single plasma mirror by analyzing the spectrum of a chirped pulse spatiotemporally overlapped with the igniting laser used for generating a plasma mirror. Experimentally, temporal contrast enhancement of 10(2) by one plasma mirror was successfully measured in a hundred picosecond timescale and was consistent with the theory. This single-shot measurement method caused no degradation on the performance of the plasma mirror, which was proved by monitoring the efficiency and far-field pattern of the igniting laser after the plasma mirror. Combined with calorimeters and CCD cameras, this method is expected to realize the single-shot online diagnosis of plasma mirrors. This method is expected to be an efficient approach for measuring the temporal contrast enhancement of the plasma mirrors.
