Enhancement of efficiency in photo-excitation to the triplet state by laser-pulse reshaping.
An optical system is proposed to enhance efficiency in photo-excitation to the triplet state by reshaping an original laser pulse into a train of pulses. This optical system can be used to improve the attainable nuclear spin polarization in dynamic nuclear polarization experiments using photo-excited triplet electron spins.
