In order to produce a highly effective microscope column with optical and pump pulses, a laser system is included in the proposed electron microscope. As a component of the microscope column, the multiple cathode structure contains a multitude of cathode regions that have been separated over a spatial level. Each region is capable of creating an electron pulse. Additionally, an electron acceleration region can be found in the microscope column, adjacent the multiple cathode structure. Also included are a specimen region and a detector.
