Abstract
Highly stable single axial mode operation is obtained in a pulsed injection seeded oscillator with an adjustable pulse length from 20 ns to more than 50 ns, at a constant output energy. The adjustment principle is described experimentally and analysed theoretically. The peak to peak time jitter added to a slow time drift is of the order of 1 nanosecond for a 20 nanoseconds pulse length.
