(a) Two-dimensional plot of the BFO (002) peak shift upon photoexcitation at 1.8 mJ cm−2 fluence. (b) Angular shift (Δθ) of the (002) peak and the photoinduced strain (Δc/c) as a function of delay up to 6 ns at the minimum delay step 100 ps. The red line represents the fit using a single component exponential function. (c) Width (FWHM) change of the 002 peak as a function of delay. |
