    "abstract": "We demonstrate experimentally that lasing in a semiconductor microstadium can\nbe optimized by controlling its shape. Under spatially uniform optical pumping,\nthe first lasing mode in a GaAs microstadium with large major-to-minor-axis\nratio usually corresponds to a high-quality scar mode consisting of several\nunstable periodic orbits. Interference of waves propagating along the\nconstituent orbits may minimize light leakage at particular major-to-minor-axis\nratio. By making stadium of the optimum shape, we are able to maximize the mode\nquality factor and align the mode frequency to the peak of the gain spectrum,\nthus minimizing the lasing threshold. This work opens the door to control\nchaotic microcavity lasers by tailoring the shape factor.",
