An electric discharge laser with an electrode unit of novel designwas developed. An electric discharge system was based onmultisectional plate-like electrodes and an automatic UVpreionisation that makes it possible to form a highly stable volumedischarge. High-efficiency lasing in N_2 and X_eF lasers wasachieved. A pulse repetition rate up to 200 Hz was realised in theN_2 laser without recourse to gas circulation.
