All-optical solid streak camera

Abstract

The invention provides an all-optical solid streak camera which solves the technical problem that large measurable dynamic range and measurable time span are difficult to realize simultaneously in the prior art. The picosecond all-optical solid streak camera with large dynamic range comprises an optical coupling system, an optical deflector and a pump light system and a reading system, wherein the optical deflector comprises an optical waveguide, and if pump light goes into the optical waveguide along vertical direction, then signal light passes through the optical waveguide along horizontal direction and is collected and read by the reading system. A functional layer of the light waveguide is an AlGaAs / GaAs / AlGaAs sandwich structure, the middle core layer is a signal light channel, and a saw-toothed pump light mask used for processing the pump light to form a light prism array in the core layer is arranged on the pump light incidence end face of the covering layer. The invention breaks through the traditional image converter tube streak camera technology based on photoelectric conversion. Meanwhile, an important scientific basis and theoretical basis is also provided for developing and pluralizing the all-optical solid streak camera technology.

Description

technical field [0001] The invention relates to an ultrafast diagnostic technology equipment, in particular to a plenoptic solid streak camera. Background technique [0002] Ultrafast phenomena (duration less than 1μs) widely appear in nature or related scientific and technological research. For example, the photosynthesis process of plants, the relaxation process of photoexcited states in optical materials, the molecular dynamics process of chemical reactions, the fluorescence emission of biological materials, the physical process of interaction between strong light and matter, and other time scales are mostly in picoseconds to femtoseconds order of magnitude, even in the range of attosecond [1] . Therefore, the study of ultrafast phenomena has a huge impetus and important practical significance for the development of natural science research such as materials, biology, photophysics, and photochemistry, as well as the progress of laser technology, intense light physics, a...
