Effects of gas molecular weights on laser opto-microengine performance are discussed in this paper. Helium, argon, and xenon are used as an environmental gas for operating of a microengine. With the decrease of the gas molecular weights, the maximum twisted torque of the microengine increases. The rotational rate of the microengine also increases with the decrease of the gas molecular weights. The twisted torque and the rotational rate of the microengine with helium are the greatest. Gas molecular motions around the microengine are numerically simulated by Direct Simulation Monte Carlo method. The numerical results by the DSMC method show that the pressure differences between forward and backward surfaces of the engine blades are dependent on the gas molecular weights. The surface temperature and rotational rate of rotating blades of the microengine were measured simultaneously.
