Abstract

Molecular orientation with combinations of near-single-cycle THz and non-resonant laser pulses is stud-ied by means of optimal control simulation with CO molecules at 5 K. We optimize non-resonant laserpulses with optimally determined final times while assuming fixed THz pulses and focusing on the carrier-envelope phase (CEP) effects. Although almost the same high degrees of orientation are achieved by thecombined control independent of CEPs, the structures of the optimal non-resonant laser pulses consider-ably depend on CEPs and the central frequencies of the THz pulses. From a practical viewpoint, simplifiedtreatments are also discussed.
