Abstract
We show that atomic gases can support solitary pulses of a unipolar el
ectromagnetic field (''EM bubbles'') with amplitude up to the atomic f
ield (similar to 10(9) V/cm) and duration down to similar to 10(-16) s
. EM bubbles propagate without dispersion, are stable, and are insensi
tive to the change of gas density. Atomic gasses can also support an E
M shock wave forming a precursor of a de ionizing field.
