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.
