In this study, we used a chirped 1.04 µm pulsed laser as a readout light and chirped 1.56 µm double pulses with the same amount and opposite sign as a test target of detection. We observed sharp pulse profiles in the sum-frequency spectrum of the two lights even though two lasers are asynchronous, and found that the achieved time resolution is less than 1 ps.
