Abstract
Direct simulation Monte Carlo was used to investigate the interaction between molecular nitrogen, argon, and methane, initially at 300 K and 0.8 atm, and frequency-chirped, pulsed optical lattices. The simulated optical lattice parameters are consistent with published optical lattice-based experiments to ensure that pulse energies and durations do not exceed optical breakdown (ionization) thresholds. In an effort to maximize optical lattice gas heating, laser pulses were chirped to produce lattice velocities which more effectively facilitate energy deposition throughout the pulse duration. The maximum end pulse translational temperature obtained in nitrogen, argon, and methane was 763, 715, and 1018 K, respectively.
