Compact high-pulse-repetition-rate XeF and KrF excimer lasers and an N{sub 2} laser with plate electrodes and the inductive-capacitance discharge stabilisation are studied. The composition and pressure of the active medium of lasers are optimised for obtaining the maximum output energy and maximum pulse repetition rate at comparatively low (no more than 19 m s{sup -1}) active-medium flow rates in the interelectrode gap. The pulse repetition rate achieved 4-5 kHz for the relative root-mean-square deviation of the laser pulse energy less than 2%. It is found that the energy of the N{sub 2}-laser pulses changes periodically under the action of acoustic perturbations appearing at high pulse repetition rates. It is shown that the use of the inductance-capacitance stabilisation of the discharge provides the increase in the maximum pulse repetition rate by 0.5-1.5 kHz (depending on the active medium type). It is found that the stability of the output energy and maximum pulse repetition rate depend on the location of preionisation sparks with respect to the gas flow direction. Some ways for the development of the technology of plate electrodes and inductance-capacitance discharge stabilisation are proposed. (lasers)
