Figure 4. Pump power dependent of the coherent phonon oscillations.

Figure 4

(a) Power dependent of the coherent phonon oscillation of 122 L sample. The pump wavelength is 400 nm and the probe wavelength is 880 nm while the probe power is 10 μW. (b) Power dependent of the amplitude of the oscillation.
