Abstract :
Tenfold enhancement in the pumping efficiency has been observed at a properly chosen pumping angle and a position in chaos-assissted nonresonant optical pumping of a deformed microcavity laser. The pumping efficiency distribution resembles the output emission intensity distribution of the deformed microcavity, consistent with the concept of the time-reversal ray tracing.
