We review the research background and development history of the generation of high-energy strong-field terahertz radiation through the tilted-pulse-front technique in lithium niobite crystals driven by femtosecond laser pulses. We systematically analyze the influence of each component in the tilted-pulse-front setup on the energy conversion efficiency and emission properties of terahertz radiation and discuss the feasibility of the generation of mJ terahertz pulses through the proposed method. Further, the numerous promising applications of strong-field terahertz sources are demonstrated.
