Abstract

Field-free alignment of N2, O2, CO, CO2, CS2, and C2H4 molecules was experimentally achieved at room temperature by using 800 nm, 110 fs laser pulses at an intensity of 6×1013 W/cm2. An enhanced degree of alignment was also demonstrated by using two pulses with appropriate separation times. These results indicate that multi-pulse alignment is a feasible approach to provide macroscopic ensembles of highly aligned molecules for practical applications.
