Abstract

The impact of thermal effects on Raman amplification in plasma is investigated theoretically. It is shown that damping and the shift in plasma resonance at finite temperature can alter the evolution of an amplified pulse. It is shown that pulse compression can occur which is not predicted by the cold plasma model. Although thermal effects can lead to a reduction in the efficiency of the interaction, this can be avoided by using a chirped pump. In this case these effects can be beneficial, suppressing the development of a train of pulses behind the amplified seed, as observed in the cold plasma model.
