Fig. 5: 3D topographic maps of femtosecond laser pulses measured by COFT based on 3D spectral holography.

From: Single-shot compressed optical field topography

Fig. 5

a Spatiotemporal distribution of the electric field of a femtosecond laser pulse from the same laser system as Fig. 2. To clearly show the peaks and valleys of the optical fields, only regions where the absolute amplitude is higher than 0.4 times the peak absolute amplitude are shown. b Temporal profile of the electric field (blue lines) at the central point \(\left( {x,y} \right) = \left( {0,0} \right)\) of the laser pulse in a, and the red dashed line shows the amplitude envelope
