Abstract
Arbitrary temporal waveform control can be achieved by means of amplifier gain control with chirped laser pulse. As lasers for fusion research are broad-band glass lasers, a chirping method of the THz region is required to obtain arbitrary temporal waveform control. In order to precisely simulate amplification properties of chirped pulse, we have developed the simulation code for an inhomogeneous glass laser amplifier. Included physics are as follows: temporal chirping; relaxation of lower level; and change of distribution density between sub-levels. Chirping (0.9 THz) applied to a Gaussian pulse increased the peak intensity of output in 20% to the case without chirping.
