我们利用方酸染料 (SQ) J 聚集体薄膜的飞秒非线性光学响应进行时空转换。泵浦脉冲和一系列四个探测脉冲分别以倾斜和垂直于薄膜平面的方向照射在薄膜的同一区域（10 mm φ）上。由于倾斜照明，泵浦脉冲与探测脉冲（间隔时间：1 ps）在不同的位置相遇。胶片通过透射率的变化挑选出每个探测脉冲的一部分，这是在空间分离的四线透射图像中观察到的。 SQ J 聚合的响应时间足以用于单次 1 THz 解复用。
We applied time-to-space conversion using femtosecond nonlinear-optical response of squarylium-dye (SQ) J-aggregates film. A pump pulse and a train of four probe pulses were illuminated on the same area (10 mm φ) of the film in direction of oblique and normal to the film plane, respectively. Due to the oblique illumination, the pump pulse met probe pulses (interval time: 1 ps) at separate places. The film picked out part of each probe pulse by its transmittance change, which was observed for a transmitted image of spatially separated four lines. Response time of the SQ J aggregates is enough for the single-shot 1 THz demultiplexing.
