    Abstract: A high-fidelity device for single-shot pulse contrast measurement based on quasi-phase-matching includes a generating unit of sampling pulse, a high-fidelity cross-correlation unit of nonlinear SFG and a high-sensitivity signal detecting unit. An innovatively designed dot-mirror or dot-attenuator and correlating crystal. The dot-mirror or dot-attenuator is adopted to suppress the scattering noise, which is mainly induced by air scattering of the main peak of the correlation beam, to a level below the real pulse background. While the crystal is introduced into the device as a nonlinear correlation crystal to move two kinds of artifacts introduced by a correlation process respectively out of the temporal window and behind the main pulse, so that effects of the artifacts on measurement results are removed and the single-shot measurement of the contrast in a pulse leading edge is accomplished, without obviously affecting other parameters. The device is also fit for measuring contrasts of high-power lasers of various wavelengths.

    Abstract: Machines and methods measure an unknown characteristic of an optical signal incident upon a detector characterized by one or more dynamic response parameters. One method receives an output signal from the detector and compares that output signal and a computationally determined response of the detector to a known optical signal incident upon the detector. The response is based on said one or more dynamic parameters. The method determines the unknown characteristic based on the comparison of the output signal and the computationally determined response of the detector. Another method receives an output signal from an optical detector detecting one or more optical signals, accesses a predetermined characteristic curve of detector response, compares the output signal from the detector to the predetermined characteristic curve of detector response, and calculates at least one unknown characteristic of one or more optical signals based on results of the comparing step.
