In order to make full use of output characteristics of high energy, ultrashort pulse width of sub-picosecond ultraviolet lasers, a calibration platform of laser inertial confinement fusion(ICF) diagnostic equipment is established. The calibration platform has such functions as laser energy measurement, optical transmission delay, beam splitting and geometric decline, and sequential optical pulse generator, which can provide the structural support and high vacuum operating environment for the relevant diagnostic equipment. The mechanical and optical design is developed in all parts of the platform, and the platform is used to calibrate the X-ray diode response time, X-ray streak camera sweep speed, X-ray framing camera dynamic range and so on. The results show that the calibration platform matches the sub-picosecond ultraviolet calibration source well, and can achieve precise calibration of various diagnostic equipments. © 2017, Chinese Lasers Press.
