Numerical simulation of output pulse shape for “Sheng uang Ⅱ”*

Abstract

Power balance between laser beams is important for high_power l aser system. This paper uses a calculation method as an exact solution for laser-amplification to simulate the output pulse shape of “Shenguang Ⅱ" laser facility. The results are preferable, as compared with the results of the experiments .

The shaped pulses control and operation on the SG-III prototype facility

“…Gain saturation in the amplifiers and the presence of frequency convertors cause a significant distortion of the pulse shape; so we construct a calculated procedure modeling these effects to produce the desired pulse. Base on different shots cycle and physical theories, the traditional procedure contains three steps [7][8][9][10]. The first step is the calculation of 1ω pulse shape required at the frequency convertors [11].…”
