35.There are other two setups, the delay line in the upper stream of the modulator in the pump light path, and the delay line in the probe light path with the modulator in the pump light path (distinction of upper/lower stream inapplicable). The treatment in Eqs. (1)–(6) needs to be modified appropriately for these cases. The final result is that the acoustic vibrations at frequencies nω0 ± Ω in the t domain are mapped into the signals at frequency nω0 in the τ domain.
36.If the delay line is in the lower stream of the modulator in the pump light path, the mapped frequency is . If the delay line is in the upper stream of the modulator in either of the pump or probe light path, the mapped frequency is nω for both USB and LSB.

We describe an extension of the time-resolved two-dimensional gigahertz surface acoustic wave imaging based on the optical pump-probe technique with periodic light source at a fixed repetition frequency. Usually such imaging measurement may generate and detect acoustic waves with their frequencies only at or near the integer multiples of the repetition frequency. Here we propose a method which utilizes the amplitude modulation of the excitation pulse train to modify the generation frequency free from the mentioned limitation, and allows for the first time the discrimination of the resulted upper- and lower-side-band frequency components in the detection. The validity of the method is demonstrated in a simple measurement on an isotropic glass plate covered by a metal thin film to extract the dispersion curves of the surface acoustic waves.
