“天光一号”装置用于状态方程的实验研究对入射光提出了很高的要求:靶上的功率密度需在1012W?cm-2以上,靶斑均匀性在3%以内。这就要求系统输出能量要尽量高,靶斑尺寸要尽量小,脉冲宽度要尽量窄,并且要将前端ASE的分布高保真地传递到靶上。而以前建立的角多路系统在某些方面无 The experimental study of the “Tianguang-I” device for the state equation puts forward high requirements on the incident light: the power density on the target needs to be above 1012W? Cm-2 and the uniformity of the target spot within 3%. This requires that the system output energy be as high as possible, the target spot size should be as small as possible, the pulse width should be as narrow as possible, and the distribution of the front end ASE must be delivered with high fidelity to the target. The previously established corner multi-channel system in some ways nothing
