On ultimate pulse repetition rates of an XeF laser

The characteristics of a repetitively pulsed XeF laser in which the velocity of the gas flowing through the discharge gap was ~55 m s^–1 were studied experimentally. The maximum power ~60 W was realised in the case of the gas mixture F₂:Xe:Ne = 3.2:16:2750 mbar and the pulse repetition rate ~4.5 kHz. When the energy supply to the discharge was lowered, the maximum pulse repetition rate ~5.5 kHz was achieved.
