【Abstract】 Based on the semi classical theory and Maxwell Bloch equations, the amplification of the seed pulse in the laser regenerative and multi pass amplifiers is analyzed. The analytical expression of the peak fluence is obtained by assuming some actual physical conditions. A relationship between the enhancement and stability of the peak output and the gain, loss of the amplifier is discussed in detail. The results are instructive to the actual establishment.更多还原
