Abstract

Numerous applications require a careful control of the phase and amplitude of pulses with GHz to THz spectral widths: coherent control of atomic systems with GHz linewidths, pulse shaping for nanosecond high-intensity laser systems or amplitude pulse shaping for pump lasers of OPCPA systems. Ultrafast pulse shapers allow the shaping, in the spectral domain, of wideband laser pulses, in the tens to hundred THz of bandwidth, on a femtosecond time scale. Ultrafast electrooptic modulators allow the shaping, in the time domain, of narrowband laser pulses in the nanosecond time scale. In between picosecond and nanosecond time scales, pulse shaping techniques are not available.
