The pulsed diffuse discharge in air at 1 atm in an inhomogeneous electric field at repetitive pulsed mode is investigated. The discharge was formed at voltage pulse amplitude of 12 kV in incident wave and a pulse repetition rate of 100-1000 Hz. It is shown that, in a wide range of experimental conditions, including those with a positive point electrode and small gaps, a diffuse discharge occurs. It is shown that, for time about 1 ns, light spots on the needle electrode and diffuse discharge in the gap were formed.
