作者演示了由纳秒紫外激光脉冲产生的时变等离子体的毫米波发射的发射频率啁啾的观测。通过使用外差干涉仪的时间分辨频率的发射从直流到交流辐射转换器源被观察到的范围从20到32 GHz的快速等离子体的创建。这种啁啾脉冲适用于各种新型的稠密等离子体诊断。
The authors demonstrated observation of emission frequency chirping of millimeter-wave emission from a time-varying plasma produced by a nanosecond UV laser pulse. By using a heterodyne interferometer the time-resolved frequency of the emission from a dc to ac radiation converter source was observed to range from 20 to 32 GHz due to the rapid plasma creation. This chirped pulse is suitable for application in various novel dense plasma diagnostics.
