385 µmD2O laser linewidth measurements to -60 dB

First linewidth measurements over a 60 dB dynamic range of a pulsed, high-power, optically pumped far infrared laser are presented. These measurements were made possible by using a 385 μmD 2 O laser with an N 2 O absorption filter and a sensitive heterodyne receiver. Studying a 385 μmD 2 O laser osc...

Zusammenfassung:First linewidth measurements over a 60 dB dynamic range of a pulsed, high-power, optically pumped far infrared laser are presented. These measurements were made possible by using a 385 μmD 2 O laser with an N 2 O absorption filter and a sensitive heterodyne receiver. Studying a 385 μmD 2 O laser oscillator we find that the low-level linewidth (
