A new way of distance measurement is introduced in this paper, it is similar to traditional measurement way, and has its origination. In the new measurement way, the rough measurement of the distance is realized by countering high frequency pulses filled in discriminable phase pulses. Discriminable phase pulses go through integral circuits, and then are sampled by Analogue Digital Converter, so the accurate measurement of the system is obtained by the sampling value.

本文提出了一种新的测距方法，该方法与常规相位测距仪比较，既有相似之处也有其创新之处，常规相位测距仪一般使用多波长测尺频率组合、差频数字测相的方法，本系统虽然也采用多波长测尺频率组合，但并不采用差频数字测相，该方法摒弃了传统的内外光路的切换方式及电路的混频，粗测采用对鉴相脉冲填充高频脉冲的办法实现，精测则利用鉴相脉冲对积分电路进行积分，然后由ADC 对积分电平进行转换，通过对ADC 的输出值的计算处理实现精测。

The research work presented in this dissertation focused on developing the scheme and techniques of OPCPA. This dissertation gives the results of the theoretical and experimental investigation on OPCPA scheme. The validation of OPCPA at high energy level was demonstrated successfully. And some important results were achieved. Several key techniques related to developing table-top ultra-intense and ultra-short OPCPA laser system were put forward, for example, the generation of femtosecond seeding pulses, the precisely temporal synchronization of the pump and signal pulses, the pulse stretching and recompression, the OPCPA process with high energy conversion efficiency and etc. Based on the integration of these key techniques, a 1.46-TW/153-fs OPCPA table-top ultra-intense and ultra-high laser system has been developed, which, to the best of our knowledge, has generated laser pulses with the shortest pulse duration and the highest peak power among the joule level OPCPA systems in the world.
