Description

technical field [0001] The invention relates to the generation technology of nanosecond pulsed light, in particular to a device and method for generating a nanosecond chirped pulse light source. Background technique [0002] Because of its high spatial and temporal resolution, pulsed light has been applied to research fields in many disciplines. For example, in biological sciences, short-pulse lasers can be used to precisely locate microorganisms and directly observe the movement of microorganisms without damage. process and perform quantitative statistics on its dynamics. In physics, pulsed light is applied to the study of the dynamic process of atoms and molecules. Therefore, the preparation of pulsed light sources is becoming more and more important and will be directly related to the research on ultrafast dynamics of microscopic substances in other fields. Nanosecond pulse light source is one of the pulse light sources with a wide range of applications. At present, th...
