A study was performed on random density inhomogeneities and focusability of the output pulses for plasma-based powerful backward Raman amplifiers (BRA). It was found that random plasma inhomogeneities can help to supress premature pump backscattering by thermal Langmuir noise. The results indicated that energetically efficient BRA is remarkably robust to the random static plasma density inhomogeneities.
