From: Photoinduced refractive index variation within picosecond laser pulses excitation as the indicator of oxyorthosilicates single crystals composition modification

Figure 4

The photoinduced variations of the total and the on-axis transmittances versus the peak laser intensity. The photoinduced variations of the total (a) and the on-axis (b) transmittances versus the peak laser intensity at 1,064 nm for the orthosilicate single crystals: 1 - LSO, 2 - LSO:Ce, 3 - LGSO, 4 - LGSO:Ce. The arrows demonstrate the impact of Ce ions incorporation on the absorptive and refractive NLO response of the LSO and LGSO crystals. The magnitudes of the peak laser intensities I t and I r correspond to the experimental dependencies slope changes.
