摘要：
This paper presents an experimental technique for measurement of the contrast ratio of ultrashort UV pulses. The multiple shot device based on the scheme of difference frequency generation is, to our knowledge, the only cross correlator in the UV so far, which offers a dynamic range of greater than or equal to 10(7) and operates with input pulse energies as low as 5 mu J. Changing the cross correlator into single shot mode, the temporal shape of the UV pulse can be measured.
