We review the work at Los Alamos regarding long pulse excimer laser operation using the technique of inductive stabilization of avalanche discharges. This technique, depending on the rate of energy deposition, has allowed laser pulse lengths of greater than 120ns and total lasing times greater than 200ns. Small lasers employing this technique are particularly useful in the control of large amplifiers to obtain narrow linewidth, near diffraction limited operation as well as in the amplification of mode-locked pulse trains to further enhance the brightness of the laser system. The performance of small lasers with short cavity length used for narrow-band frequency tuning, active modelocking and the advantages associated with high repetition rate operation will be discussed. The scaling to longer gain lengths and to high average power systems will also be discussed. Finally, a brief discussion of the potential uses of small long pulse devices in the areas of high brightness sources, medical and semiconductor applications will be given.
