The invention provides a resonant cavity and a terahertz extended interaction oscillator of a cross structure. The terahertz extended interaction oscillator of the cross structure is greatly differentfrom a traditional terahertz extended interaction oscillator. In a conventional device, a longitudinal electric field is distributed in one direction (such as an x-direction or a y-direction) in a concentrated manner; while a longitudinal electric field is distributed in two directions (i.e., the x-direction and the y-direction) at the same time in the device of the cross structure. Therefore, inthe structure, the energy exchange efficiency of the longitudinal electric field and the cylindrical electron beam can be effectively enhanced, and the output power can be effectively improved. The device can work under the working conditions of 14kV and 0.1 by optimally designing the cross extended interaction oscillator working at 0.3 THz, and the power output of about 51.5 W can be realized. The cross structure is suitable for improving the output power of the terahertz extended interaction oscillator, and is particularly suitable for improving the engineering realizability and the workingstability of a device under lower working current.
