Paper Abstract

The high repetition rate UV lasers (XeF [1], KrF [2] and N2) with a new electrode unit are investigated. A multisectional discharge gap 25 cm length and 1.2 cm height is formed by 25 pairs of anode-cathode plates. The discharge width is ≈ 1 mm. The average specific pump power is ≈ 9 MW cm-3. The main aim of the work is the achievement of a maximum pulse repetition rate (fm) with high output energy stability. At a rather low gas flow velociity ⩽ 19 m s-1 the frequencies f as high as 4 kHz in the excimer lasers and 4.5 kHz in a nitrogen laser are realized. The relative rms deviations of the output energy (&sgr;) for XeF and KrF lasers is in the range 1-2% for f ⩽ 3 kHz and 3-4% for f = 4 kHz. For the nitrogen laser &sgr; ⩽ 1.3% is at f ⩽ 4.5 &kgr;&Ggr;ц.The average output power 10 (12) W for the XeF (KrF) laser and 1.1 W for the nitrogen laser are reached.
