编辑总结如下：

He identifies two milestones in the development of THz sources — the generation of THz pulses from short laser pulses and the development of the THz quantum cascade laser. He envisages that the next breakthrough in the field could be the development of high-intensity THz sources. He says that non-destructive THz imaging is highly promising for meeting the current demands in the areas of security and quality control. He also considers that combining different technologies, such as electronics and plasmonics, is important for realizing novel THz systems that offer orders of magnitude improvements in performance at a fraction of the cost of existing systems.
