Abstract

The results of the development of a technique for measuring the power contrast of a laser pulse by registering the pulse-front profile with a large dynamic range are presented. The technique was developed on the basis of a high-speed streak camera and fiber-optic transmission lines; it provides the following registration parameters: the dynamic range of measuring the laser-pulse power contrast at the wavelength λ = 0.53 µm is 107, while the temporal resolution of the registration channel is no worse than 60 ps. A method of increasing the power contrast to 1011 using an optical scheme based on elements with nonlinear transmission is shown.
