为研究众多因素对高功率固体激光装置输出功率平衡的影响, 利用已建立的功率平衡综合分析模型初步分析了正在建造的最大固体激光装置的功率平衡问题。介绍了模型的建立过程、功能特点和主要算法。数值模拟分析了使用单一Haan脉冲波形条件下系统偏差和随机偏差对装置输出功率平衡的综合影响。结果表明, 在补偿系统偏差后, 注入能量抖动3%, 放大器增益抖动15%和频率转换失谐角抖动2%的条件下, 使用单一Haan脉冲能满足总的功率平衡要求。最后根据数值计算结果对随机偏差指标进行了初步分解。

To investigate the effects of a number of factors on the output power balance of high-power solid-state laser facility, the power-imbalance problem of the largest solid-state laser facility which is now building in our country was preliminarily analyzed by the integrated analytic model for multi-beam laser power balance which has been developed. First the setup procedure, the functional characteristics and the main algorithms of the model were introduced. Then, the integrative influence of systematic and random deviations on opower balance was analyzed by single Haan pulse. The results showed that the power imbalance of the facility can be satisfied on condition that the systematic deviations were fully compensated, and the jitter of injection energy was 3%, and the jitter of amplifier gain coefficient was 1.5%, and the jitter of doubling-crystal detuning angle was 2%. Finally, the random-deviation specification was preliminarily allocated according the numerical calculation.
