Abstract
This present disclosure describes a method, a device, and a system for performing a pulse shaping method that accurately converts short laser pulses into arbitrarily programmable optical waveforms with much longer duration. The optical pulse shaping method is based on multi-frequency acoustic-optic modulation and retro-diffraction based multiple optical delay line generation. Regarding the optical pulse shaping method, precise high-speed programming control on amplitudes, phases, and delays of a picosecond ultrashort sub-pulse sequence is implemented, to obtain an arbitrary waveform optical pulse with a near-THz bandwidth and a coherence time up to nanoseconds, for applications in quantum control of atomic/molecular optical transition.
