Abstract :
We have measured pumping efficiency experimentally in a deformed microcavity laser. We observed a tenfold enhancement in the pumping efficiency via chaos-assisted nonresonant optical pumping at properly chosen pumping angle and position. When the pump wavelength was scanned at the optimal pumping angle and position in a manner of excitation spectroscopy, we observed an additional hundredfold enhancement when the pump wavelength was resonant to a cavity mode spatially overlapping much with the lasing cavity mode.
