A 0.8% efficiency, low-pressure Blumlein-type nitrogen laser is described. To the authors' knowledge, this is the highest observed efficiency for nitrogen lasers employing the traditional Blumlein circuit of excitation. The good efficiency is attributed to the optimization of the discharge chamber geometry and to the use of a low inductance spark gap (< 10 nH). The laser provides pulses with energies greater than 5 mJ and pulse widths not exceeding 4 ns; the design is simple in construction and operation. Stable operation is achieved for voltages ranging from 8 to 14 kV, pressures between 70 and 250 torr, and frequencies limited to 20 Hz.
