Web4 jun. 1998 · We have developed a prototype normal‐conducting, x ‐band, pulse‐compression cavity in which the prepulse is suppressed by more than 70 dB. When this cavity is driven by a 20‐kW source, output pulses with 200‐kW peak power, 5‐ns pulse width, and sub‐nanosecond rise time can be obtained. WebThe pulse of a coherent oscillator can be compressed by a plasma filled waveguide. The idea is to change the plasma properties in time, as the pulse enters, so that a frequency …
