基于气体染料激光器的均匀光斑输出特性，建立了一套亚皮秒紫外标定装置。该系统可以产生波长为248.5 nm，脉宽约为0.5 ps，总能量约为100 mJ，大小约为35 mm×25 mm的均匀光斑。利用该系统成功实现了高时间分辨惯性约束聚变诊断系统的初步标定。结果表明，新建立的亚皮秒紫外标定装置可以满足皮秒系统的精密标定需求，并且利用系统稳定的能量输出特点，有望发展定量化的时间分辨定标技术。

A sub-picosecond ultraviolet calibration facility is established based on the uniform profile of a gas dye laser, and this is specially designed for the inertial confinement fusion diagnosis system calibration. The laser beam operates at 248.5 nm with a pulse width of about 0.5 ps and a total energy of about 100 mJ, and generates a uniform spot that is about 35 mm×25 mm. Some preliminary calibration results of a high temporal resolution diagnosis system are obtained on the facility, which proves that the parameters of picosecond systems can be calibrated on the facility. Since the energy output is stable, it is possible to develop a quantitative time-resolving calibration technique.
