英文摘要： Owing to the space-charge effect and infrared detection insensitivity existing for conventional vacuum streak tube camera, a new all-optical solid-state streak camera is demonstrated. This camera not only has high stability, good performance, and also has an extended infrared spectroscopic response.It will find wide range applications in the fields such as material, physics, biology, chemistry. Our group intends to carry out theoretical research and engineering design of all-optical solid-state streak camera. We will study the mechanism of all-optical solid-state streak camera, and design this new all-solid-state streak camera system, including optical coupling system, light deflection system, the pump light system and the readout system, and characterize the main parameters of all-optical solid-state streak camera so as to improve the key technical index. Ultimately, we can obtain an all-optical solid streak camera with picosecond-scale temporal resolution, 1000-100000 measurable dynamic range, 0.9-25 micron infrared spectral response range as well as a few hundred picoseconds measurable time-span.
