激光单脉冲时-空采样器的研究

Research on the temporal-spatial detector of laser parameters measurement for single pulse

分析了激光单脉冲时_空实时测量对时_空采样器的要求,提出了在高峰值功率密度下探测器设计的“梳导”思想,讨论了用不同长度的单模光纤束制作时_空采样器的关键技术和工艺。这种时_空采样器具有高带宽、高损伤阈值、高捕获率的优点。

The requirements of temporal-spatial measurement were discussed for ns-laser parameters of single pulse. A ＂tiny comb＂ idea to design detector used in high peak power density measurement was proposed. Facture techniques of sampler detector were discussed by one sampling with a bunch of single-mode fiber which was designed in serial number with different length. Its advantages are high damage threshold, high acquirement rate and real temporal-spatial domain sampling.
