Different applications of ultrashort laser pulses in signal processing, imaging and cryptography are discussed. The detection of complex amplitude of a single ultrashort optical pulse is important for various diagnostics applications. The spatial image has one-to-one correspondence with the signal pulse, implementing the desired time-to-space demultiplexing at femtosecond rates, with short pulses. The inverse time-to-space transformation for detection of femtosecond pulse sequences is achieved using nonlinear three-wave mixing.
