Fig. 1.. Square radius, r2, of the crater produced by the fs pulses as a function of the pulse energy, E, at three different number of pulses namely N = 40, 100, 1000. Solid lines are fits to the expected dependence from which the laser modification threshold of CdZnTe and beam spot size are obtained. The inset reports the variation of the fluence threshold Fth with the number of pulses N in the form:$N{{F}_{\text{th}}}\left( N \right)={{F}_{\text{th}}}\left( 1 \right){{N}^{\xi }}$, with single shot fluence threshold Fth(1)=(14 ± 1) mJ/cm2 and incubation factor ξ=(0.80 ± 0.05).
