氯化亚铜蒸气激光器用于高分辨率、无快门高速摄影

A Cu/CuCl Vapor Laser Used in High Resolution No Shutter High Speed Photography

缓冲气体流动的氯化亚铜蒸气激光器发出波长5106A和5782A、脉宽20ns、光脉冲能量0.45mJ、光脉冲功率20kW的高重复率光脉冲。本文首次报道了用这种激光拍摄静态和动态目标的试验,获得较清晰的分幅照片。其优点为分辨率较高、不需要快门和象移的光学补偿。因此,此激光器可作为一种高速摄影光源。

A Cu/CuCl vapor laser with flowing buffer gas emitted highrepetition rate light pulses with the wave length 5106A and 5782A, FWHM 20ns, light pulse energy 0. 45mJ, light pulse power 20kW. High speed photogra-phic experiments on the static and dynamic objects were carried out using theCu/CuCl vapor laser for the first time and comparative clear individual photoswere obtained. The advantages of this light source were: high resolution,no shutter and no need of optical motion compensation unit. The Cu/CuCl va-per laser may be used as a light source of high speed photography.
