Experimental demonstration of pulse characterization in the picosecond and sub-picosecond regimes

The reliable characterization of ultrafast laser pulses is essential for science and technology, yet conventional nonlinear techniques such as second-harmonic autocorrelation or FROG/SPIDER require relatively high pulse energies and complex instrumentation. This thesis presents the experimental vali...
