Abstract

The interaction area of high-intensity tightly-focused 1078 nm pulses of 30 ps duration with CVD diamond film has been studied using second harmonic (540 nm, 20 ps) unfocused beam for backlighting. The 2D spatial distribution of energy density of probe radiation passed through the tested sample was recorded that allowed to measure the transient relative transmittance of the laser-affected zone as a function of temporal and spatial coordinates. The pump-probe interferometric measurements of laser induced refractive index in fused silica glass done with micron spatial and picosecond temporal resolution are also presented and discussed.
