Paper Abstract

Discharged-pumped excimer lasers[1] with a compact type[2], high repetition rate[3], long life time operation[4] are required for the laser sources for lidar application[5]. The physical conditions include, above all, the retention of homogenity of the discharge volume at a high pulse repetition frequency for this laser. This is usually done by replacing the gas in the electrode gap which refines circulation by various fan systems. The stable discharge and the high velocity of a few ten m/s are necessary for the kHz order repetition-rate laser[6]. For this purpose, we have developed a compact KrF excimer laser of cylindrical cage structure and investigated the characteristics of laser output, repetitive operation and long life from this system.
